Hello!

Attached patch enables building of TCmode complex functions from
libgcc2 for cygwin, darwin and freebsd targets. The patch also removes
linux64.h defines since these are already defined in linux.h.

2010-09-01  Uros Bizjak  <ubizjak@gmail.com>

	PR target/45476
	* config/i386/darwin.h (LIBGCC2_HAS_TF_MODE, LIBGCC2_TF_CEXT, TF_SIZE):
	New defines.
	* config/i386/freebsd.h (LIBGCC2_HAS_TF_MODE, LIBGCC2_TF_CEXT, TF_SIZE):
	Ditto.
	* config/i386/linux64.h (LIBGCC2_HAS_TF_MODE, LIBGCC2_TF_CEXT, TF_SIZE):
	Remove defines.
	* config/i386/cygming.h (LIBGCC2_HAS_TF_MODE, LIBGCC2_TF_CEXT, TF_SIZE):
	Move from ...
	* config/i386/mingw32.h: ... here.

Patch was bootstrapped on x86_64-pc-linux-gnu. Can please relevant
target maintainers check if everything is OK on their targets?

Uros.
