acinclude.m4 (GLIBCXX_ENABLE_C99): Test for complex math functions... 


2005-01-25  Benjamin Kosnik  <bkoz@redhat.com>

	* acinclude.m4 (GLIBCXX_ENABLE_C99): Test for complex math
	functions, and enable _GLIBCXX_USE_C99_COMPLEX_MATH if they exist.
	* acconfig.h: Add _GLIBCXX_USE_C99_COMPLEX_MATH.
	* config.h.in: Regenerate.
	* configure: Regenerate.
	* include/std/std_complex.h: Protect complex builtins with
	_GLIBCXX_USE_C99_COMPLEX_MATH.
