Merge branch 'yacc-work' into yl-work-for-master
* yacc-work: (37 commits)
fixup: list of yacc/lex tests was botched
tests: work around bug#7884 in many yacc/lex tests
yacc/lex tests: remove an unneeded workaround for bug#8485
yacc/lex tests: avoid too much failures with FreeBSD make
yacc-dist-nobuild.test: add reference to bug#7884
yacc tests: fix bug in 'yacc-cxx.test'
lex tests: fix spurious link errors on Solaris
lex: "make clean" removes .c files from non-distributed .l
lex tests: make test on Lex dependency tracking more "semantic"
lex tests: remove erroneous check about ylwrap distribution
yacc tests: "make clean" removes C++ files from non-distributed .y
tests: add a workaround for automake bug#8485
tests: add a couple of inter-tests reference
lex tests: require just `lex' instead of `flex'
fix typo in ChangeLog (2011-05-04)
tests defs: use `skip_' for skipping yacc/lex related tests
lex/yacc tests: remove redundant $distdir definition
coverage: test lex-generated "#line" directives postprocessing
tests: minor improvements to a couple of yacc tests
tests: fix spurious failure in test 'yacc-d-cxx.test'
...
+ Extra non-trivial edits:
* tests/defs.in: Delete; the differences from maint has been
merged into 'tests/defs' and 'tests/defs-static.in'.
* tests/defs (yacc, lex): Use 'skip_all_', not 'skip_', to
skip the whole test case if yacc (resp. lex) is missing.
(bison): New, set up the environment so that 'bison -y' will
be used as the yacc program.
(useless_vpath_rebuild, yl_distcheck): Moved in from
'tests/defs.in'.
* tests/defs-static.in ($YACC, $LEX): Default to the values
determined at configure time, and allow them to be overridden
by the more namespace-safe variables '$AM_TESTSUITE_YACC' and
'$AM_TESTSUITE_LEX' respectively.
* tests/Makefile.am (do_subst): Also substitute '@YACC@' and
'@LEX@'.
* Several tests: Fix requirements declarations, by preferring
'lex' and 'yacc' over 'flex' and 'bison' whenever possible.

tests: fix spurious failures due to missing 'yywrap()' function
The AC_PROG_LEX Autoconf macro does not diagnose a failure to find
the "lex library" expected to provide a `yywrap' function (function
which is required to link most lex-generated programs). On the
contrary, when all the link attempts (i.e., with `-ll' and `-lfl')
fail, configure declares that no lex library is needed, and simply
proceeds with the configuration process -- only for the build to
possibly fail later, at make time.
This behaviour is intended; the Autoconf manual reads:
``You are encouraged to use Flex in your sources, since it is
both more pleasant to use than plain Lex and the C source it
produces is portable. In order to ensure portability, however,
you must either provide a function `yywrap' or, if you don't use
it (e.g., your scanner has no `#include'-like feature), simply
include a `%noyywrap' statement in the scanner's source.''
This AC_PROG_LEX behaviour is causing some spurious failures of
the Automake testsuite in environments which lack a proper library
providing `yywrap' (this happens for example on Fedora-based
systems). The proper workaround is to simply provide a fall-back
implementation of `yywrap' in our lexers.
See also partially-overlapping commit `v1.11-871-geb147a1' (from
the 'testsuite-work' branch), which was motivated by similar
spurious failures experienced when cross-compiling.
Reported by Jim Meyering:
<http://lists.gnu.org/archive/html/automake-patches/2011-10/msg00092.html>

lex tests: avoid possible hang; fix and extend
* tests/lex3.test (foo.l:yywrap): Return 1, not 0, to avoid hangs.
Bug introduced in commit 'v1.11-871-geb147a1'.

our own `yywrap' function.

consistency with the default flex implementation.

library, if that's available.

lex tests: avoid spurious failures when LEXLIB isn't found
The AC_PROG_LEX Autoconf macro does not diagnose a failure to find
the "lex library" expected to provide a `yywrap' function (function
which is required to link most lex-generated programs). On the
contrary, when all the link attempts (i.e., with `-ll' and `-lfl')
fail, configure declares that no lex library is needed, and simply
proceeds with the configuration process -- only for the build to
possibly fail later, at make time.
This behaviour might be (partly) intended; the Autoconf manual
reads:
``You are encouraged to use Flex in your sources, since it is
both more pleasant to use than plain Lex and the C source
it produces is portable. In order to ensure portability,
however, you must either provide a function `yywrap' or, if
you don't use it (e.g., your scanner has no `#include'-like
feature), simply include a `%noyywrap' statement in the
scanner's source.''
This AC_PROG_LEX behaviour is causing some spurious failures of the
Automake testsuite in environments which lack a proper library
providing `yywrap' (this happens for example in Linux->MinGW cross
compilations). But at this point is clear that a proper workaround
is to simply provide a fall-back implementation of `yywrap' in our
lexers.

testsuite: require C compiler explicitly in tests needing it
The list of the test scripts which needed a C compiler but

tests: do not uselessly require GNU make or gcc in a few tests
* tests/lex3.test: Remove gcc from requirements, as any working C
compiler should be ok. Consequently, do not clobber user CFLAGS.
Also, remove GNUmake from requirements; it was added (see commit
`Release-1-8-103-g0d2f592') because this test fails with FreeBSD
make due to VPATH issues -- but so do many other yacc-related and
lex-related tests currently, and requiring GNU make in all of
them would unacceptably reduce coverage.
* tests/lexvpath.test: Remove gcc from requirements, as any
working C compiler should be ok.
* tests/yacc4.test: Likewise.
* tests/yacc8.test: Likewise.

make; to compensate, explicitly call "$MAKE Makefile" to update

Extend, fix and improve tests on Lex and Yacc support.
* tests/lexcpp.test: New test script, on support for Lex + C++.
* tests/lexvpath.test: New test script, test build and rebuild
rules for lexers in VPATH setup.
* tests/yacc-basic.test: New test script, run simple "semantic"
checks on basic Yacc support (similarly to what lex3.test does
for Lex support).
* tests/lex.test: Don't create useless dummy source file joe.l.
Remove extra blank lines.
* tests/lex4.test: Add trailing `:' command. Do not create dummy
useless lex source file.
* tests/lex2.test: Likewise. Call automake with the `-a' option,
so that it doesn't fail for the absence of `ylwrap' script. Make
grepping of automake stderr stricter.
* tests/yacc7.test: Add trailing `:' command. Enable `errexit'
shell flag earlier (just after having sourced ./defs).
* tests/yacc4.test: Likewise. Also ...
(configure.in): Use pre-populated skeleton set up by ./defs,
instead of writing one from scratch.
Other minor cosmetic changes.
* tests/yacc5.test: Likewise.
* tests/yaccvpath.test: Likewise. Also ...
($distdir): New variable.
Use it throughout.
* tests/lex5.test: Likewise.
* tests/lex3.test: Likewise. Check the distdir, rather than
grepping the distribution tarball. Extend the test on the
created binary, and be sure to avoid hangs. Add some comments.
* tests/yacc.test: Use stricter grepping. Add trailing `:'.
* tests/yacc6.test: Likewise.
* tests/yacc3.test: Likewise. Do not create the unused file
`Makefile.sed'. Remove useless rules from Makefile.am. Other
minor cosmetic changes.
* tests/yacc2.test: Make grepping of generated `Makefile.in' and
of automake error messages stricter. Do not redirect output of
grep to /dev/null. Move call to aclocal earlier. Reduce the
number of empty blank lines. Fix a typo in comments.
* tests/yacc8.test: Fixed bugs that reduced the completeness of
the tests. Added trailing `:' command.
(configure.in): Use pre-populated skeleton set up by ./defs,
instead of writing one from scratch.
* tests/yaccpp.test: Test also extensions `.y++', `.ypp', and
`.yxx', rather than only `.yy'.
* tests/Makefile.am (TESTS): Update.
