SCO OpenServer 5.0.5, SCO dev sys
>Description:
gcc-3.1 builds under SCO OpenServer 5.0.5 using the SCO
dev sys fail with
"machmode.def: undefined symbol: BITS_PER_UNIT".
Reverting the ChangeLog entry below would probably fix
the problem.

>       * config/i386/sco5.h(i386.h, att.h): Eliminate double inclusion.
The ChangeLog for gcc-3.2 does not have any indications that
this has been fixed.
>How-To-Repeat:
Build gcc-3.1 under SCO OpenServer 5.0.5 with the SCO dev sys.
It will probably happen on all versions of SCO OpenServer 5.
>Fix:
I built gcc-3.2 using the patch below.
