[Bug c/14437] New: 3.3.3 release does not build for target i686-wrs-vxworks

["mfhaigh at acm dot org" <gcc-bugzilla at gcc dot gnu dot org>]

When building for i686-wrs-vxworks, the following error occurrs:

/cygdrive/c/DOCUME~1/ADMINI~1/LOCALS~1/Temp/ccEKfcPb.s: Assembler messages:
/cygdrive/c/DOCUME~1/ADMINI~1/LOCALS~1/Temp/ccEKfcPb.s:282: Error: no such
instruction: `mulhwu %esi,%esi,%ecx'

This is because vxWorks always defines the PPC macro, regardless of target,
which confuses gcc/longlong.h into emitting PPC assembly (the PPC macro clashes
with the GNU/Linux and SysV usage of it).  The solution is to undef PPC for
vxWorks, and use a more appropriate macro for deciding when to emit PPC assembly.

I believe I have the proper patch for this, and it will be posted to the mailing
list shortly.
