Hi,

this patch fixes this issue.  Is it OK ?

Maybe we should include the AC_DEFINE action within GCC_CHECK_MATH_FUNC.  Will try to do that.

Sorry for not having noticed this issue before.

Tristan.

libgfortran/
2012-03-27  Tristan Gingold  <gingold@adacore.com>

	* configure.ac: Add description to AC_DEFINE in
	GCC_CHECK_MATH_FUNC.
	* configure: Regenerate
	* config.h.in: Regenerate.

That looks like a cleaner solution, yes, and less chance for typos to sneak in.

No problem. Thanks for fixing it quickly.

No check-gfortran regressions on x86_64-darwin, committed.
