Preprocessor failure

[Edouard Gomez]

Hello,

Let me first introduce myself. I'm a xvid[1] developer, and during a bug
hunting session  for pe-i386 object  format from nasm  + GNU ld  2.14, i
tested a bit yasm as it's compatible with the nasm parser.

So i would like to support yam in XviD, but i run into some problems:
 - current tarball does not have -D options that XviD uses
   -> fixed in CVS that has -D option
 - yasm  seems to  work fine  on the  bug i've  been tracking[2]  as the
   pe-i386 object file is right.
   -> good point for yasm
 - yasm is a  bit pedantic on some usual things  like trailing commas on
   data definitions like:
   dw 1, 2, 3, 4, <-- will panic the parser
   dw 1, 2, 3, 4
   -> This obliges  me doing some code  cleanup in our  nasm files, it's
   just annoying but not a bug.
 - yasm refuses equ symbols in macros
 - yasm fails  at least  one file (reduced_mmx.asm[3]).   The assembling
   error is outstanding, line 928 has no pcmpgtw opcode.
   -> bug

Then i stoped.

$ make
  A: image/x86_asm/reduced_mmx.asm
../../src/image/x86_asm/reduced_mmx.asm:396: label or instruction
expected at start of line ../../src/image/x86_asm/reduced_mmx.asm:396:
duplicate definition of `pcmpgtw'; first defined on line 928

I won't  commit code cleanups for yasm  support to xvid cvs  until i get
the complete files assembled. That's why  i post here this bug report so
we can come up with a working yasm XviD.

And sorry for just offering you bug  report and no patch, but my time is
quite limited this last weeks.
