Benjamin Kosnik 5e90dd7193 std_complex.h: Tweaks, include cmath for abs overloads. 
2000-11-20  Benjamin Kosnik  <bkoz@redhat.com>

	* include/bits/std_complex.h: Tweaks, include cmath for abs overloads.
	* src/complex.cc: Remove cmath include, formatting tweaks, remove
	dead code.
	* include/c/bits/std_cmath.h: Formatting tweaks.
	* testsuite/26_numerics/complex_value.cc: New file, for catching
	bits gleaned from libstdc++/106.

	* testsuite/23_containers/vector_ctor.cc (test02): Add test from
	libstdc++/102.
