[This]patch is a bit more involved. The patch addresses a gcc
regression in the 4.3 series (specifically this patch is against 4.3.2
which does *not* have a lot of other issues which affect kernel building)

GCC bug tracker has this issue as
#38453 http://gcc.gnu.org/bugzilla/show_bug.cgi?id=38453
#32044 http://gcc.gnu.org/bugzilla/show_bug.cgi?id=32044

comment 65 of #32044 has the fix being applied to gcc trunk as revision #142719

The attached patch is a backport to gcc 4.3.2 which allows this
version to be used to generate correct output for various ARM kernel
build (and indeed is teh correct answer in general).

     1 [ Building gcc-2.95.3 on cygwin yields a compiler that sticks a .exe

     2   on the end of every executable, even if they're linux executable.

     3   This is highly annoying, and causes glibc build failures that look like this:

     4     mv: `.../bin/makedb.new' and `.../bin/makedb' are the same file

     5     make[2]: *** [.../bin/makedb] Error 1

     6     make[2]: Leaving directory `.../gcc-2.95.3-glibc-2.1.3/glibc-2.1.3/db2'

     7 

     8   The mainline solves this with http://gcc.gnu.org/ml/gcc-cvs/2001-04/msg00440.html,

     9   but that doesn't apply cleanly to gcc-2.95.3.

    10 

    11   So, I'm using

    12   http://www.uclinux.org/pub/uClinux/uclinux-elf-tools/tools-20030314/gcc-2.95.3-cygwin-020611.patch

    13   This is the only patch in crosstool that *isn't* suitable for the mainline.

    14   I can live with this patch simply because crosstool does not build

    15   compilers that target cygwin or VAX/VMS. 

    16   If that ever changes, I might need to try applying the real patch.
