Is there a way to check the minor-minor GCC version?
gcc provides __GNUC_PATCHLEVEL__ but the test suite doesn't use it.
In lib/compiler.c and lib/compiler.cc you could edit:
-set compiler_info [join {gcc __GNUC__ __GNUC_MINOR__} -]
+set compiler_info [join {gcc __GNUC__ __GNUC_MINOR__ __GNUC_PATCH_LEVEL__} -]
Test before-and-after; for extra style, change the existing 39 calls
to test_compiler_info:
gcc-2-* gcc-2-*-*
gcc-*-* gcc-*-*-*
et cetera
One gotcha: __GNUC_PATCHLEVEL__ is not available in gcc 2.95.3. I think
this is okay because the compiler_info string will just expand to
"gcc-2-95-__GNUC_PATCHLEVEL__" so as long as no one is looking to
distinguish between gcc 2.95.2 and gcc 2.95.3 it's okay. Tests for
"gcc-2-*" or "gcc-2-*-*" ought to work. This gotcha will need a comment
though. (The gcc doco for 3.3.3 says that __GNUC_PATCHLEVEL__ was
introduced with gcc 3.0 and also works in gcc 2.96 and gcc 2.97).
You could do this, or file a PR and I'll do it.
