The change to t-crtfm is OK.
(Other changes should be reviewed by mingw maintaner.)

The mingw32 specific changes are OK for 4.2.1.
Uros, does your approval for t-crtfm also apply to the the
libgcc/config/i386/t-crtfm, on trunk?
If so I will also apply the corresponding changes to trunk. (Bootstap
and regtested there on i686-pc-mingw32)

Yes it covers both files. I missed the fact that these files should be
kept in sync; -minline-all-stringops should also be added to libgcc's
t-crtfm (BTW: I think that this is a nice change for all targets).
Thanks,
Uros.

This is what I have committed to trunk, after bootstrap and regtest on
i686-pc-mingw32 and i686-pc-cygwin
and build on i686-pc-linux
I have not yet backported to 4.2.1.

It is waiting for someone to commit it to SVN. I can't test it on
mingw target, but if it works for you, I'll commit it to SVN.

Hi,
This patch ports http://gcc.gnu.org/ml/gcc/2005-08/msg00281.html to mingw32.
It does mostly what the Linux counterpart did, but MinGW32 doesn't inline
__builtin_memset and putting crtfastmath.o in endfile spec causes linker to
fail so -minline-all-stringops is added on purpose.
