Use AM_CONDITIONAL and if/endif for AMDEP.
* m4/depend.m4 (AM_DEP_TRACK): Use AM_CONDITIONAL to define AMDEP.
* automake.in (&add_depend2): Transform %AMDEP% into `AMDEP' (leading
to a configure time if/endif), or to `FALSE' (static removal of
the code).
(&handle_dependencies): Adjust to use `AMDEP_TRUE'.
* depend2.am: Use if/endif.
Adjust the 101 tests that use dependencies so that they
properly invoke aclocal before automake. They need to `see'
`AM_CONDITIONAL([AMDEP], ...)'.
* specflags3.test: New file.
* Makefile.am (TESTS): Added specflags3.test.
(TESTS): Now lists one file per line, for simpler maintenance.
* specflags2.test: New file.
* specflags.test: New file.
* Makefile.am (TESTS): Added specflags.test, specflags2.test.
