  Modernize, improve and extend tests for PR (`pr[0-9]*.test').
  
  * tests/pr2.test: Add trailing `:' command.
  * tests/pr229.test: Likewise.
  * tests/pr401.test: Likewise.
  * tests/pr401b.test: Likewise.
  * tests/pr401c.test: Likewise.
  * tests/pr300-prog.test: Likewise, plus cosmetic changes in
  spacing.
  * tests/pr300-lib.test: Likewise.
  * tests/pr300-ltlib.test: Likewise, and ensure verbose printing
  of captured make stdout.
  * tests/pr211.test: Add trailing `:' command.  Also, use the
  `configure.in' stub created by ./defs, rather than writing it
  from scratch.
  * tests/pr204.test: Likewise, plus cosmetic spacing changes.
  * tests/pr287.test: Likewise, and move setting of `errexit' shell
  flag earlier in the script (just after inclusion of ./defs).
  * tests/pr220.test: Make grepping of Automake's stderr stricter.
  Also, add trailing `:' command, and cosmetic changes in spacing.
  * tests/pr224.test: Move setting of `errexit' shell flag earlier
  in the script (just after inclusion of ./defs).  Do not export
  `CC=gcc' to configure explicitly (it's already exported globally
  in ./defs, since we have "gcc" in $required).  Use the stub for
  `configure.in' created by ./defs, rather than writing it from
  scratch.  Do not create dummy files required by "gnu" mode (e.g.
  README, NEWS), since we run automake in foreign mode anyway.
  * tests/pr72.test: Enable `errexit' shell flags, and related
  changes.  Extend existing checks a bit.
  * tests/pr9.test: Likewise.  Also, avoid obolescent constructs in
  the generated `configure.in', and extend existing checks over the
  generated tarball a bit.
  * tests/pr87.test: Enable `errexit' shell flags, and related
  changes.  Add a trailing `:' command.  Also, do not create dummy
  files required by "gnu" mode (e.g. README, NEWS), since we run
  automake in foreign mode anyway.
  * tests/pr243.test: Avoid obolescent constructs in the generated
  `configure.in'.  Enable the `errexit' shell flag, and related
  changes.  Cosmetic changes to spacing, add trailing `:' command,
  and add a "FIXME" comment.
  * tests/pr266.test: Likewise, and add explicit command line switch
  `--enable-dependecy-tracking' to the ./configure call.
  * tests/pr279.test: Avoid obolescent constructs in the generated
  `configure.in'; also, use the `configure.in' stub created by
  ./defs, rather than writing it from scratch.  Enable `errexit'
  shell flag, and related changes.  Add trailing `:' command.
  * tests/pr279-2.test: Likewise, and make grepping of Makefile.in
  stricter.
  * tests/pr307.test: Move setting of `errexit' shell flag earlier
  in the script (just after inclusion of ./defs).  Escape literal
  dots in grep regular expressions.  Also, add a trailing `:'
  command, and cosmetic changes to spacing.

  # Test for PR 307: depcomp with depmode=dashmstdout libtool race condition
  # Report from Laurent Morichetti.
  # (Also exercises check_LTLIBRARIES.)
  #
  # == Report ==
  #  The dashmstdout depmode calls libtool in parallel to generate the
  #  dependencies (with -M flag) and to build the objfile (both have
  #  --mode=compile and -o).
  #  The process with 'libtool --mode=compile .* -M' can corrupt the objfile
  #  as none is generated by the compiler.  Since --mode=compile and -o are
  #  set libtool assumes that a objfile should be generated and will execute
  #  invalid $mv & $LN_S.
  #
  # == Fix ==
  #  Now 'depcomp' never compute dependencies in the background, as this can
  #  cause races with libtool.  Compute the dependencies after the actual
  #  compilation.
