	* testsuite/Makefile.am (all-local): Add conditional rule to
	generate testsuite_wchar_t.
	* testsuite/Makefile.in: Regenerate.
	* testsuite/lib/libstdc++-v3-dg.exp
	(libstdc++-v3-list-sourcefiles): Remove wchar_t files if
	testsuite_wchar_t is not present in the build directory.
	* testsuite/libstdc++-v3.dg/dg.exp: Add -g -O2 to DEFAULT_CXXFLAGS.
	Remove setulimit bits.
	* testsuite/26_numerics/complex_value.cc: Set to noopts.
