acinclude.m4 ([GLIBCXX_ENABLE_C99]): Add ac_c99_complex to the final test for enable_c99, thus robustifying it...

2005-01-26  Paolo Carlini  <pcarlini@suse.de>

	* acinclude.m4 ([GLIBCXX_ENABLE_C99]): Add ac_c99_complex
	to the final test for enable_c99, thus robustifying it; remove
	duplicate final test on ac_99_math.
	* configure: Regenerate.

	* include/std/std_complex.h: Remove usages of the dead
	_GLIBCXX_BUGGY_COMPLEX macro.

	* testsuite/26_numerics/cmath/19322.cc: Protect with
	_GLIBCXX_USE_C99_MATH instead of the stronger _GLIBCXX_USE_C99,
	since only C99 math facilities are involved.
	* testsuite/26_numerics/cmath/c99_classification_macros_c++.cc:
	Likewise.
