OK, I'm trying to compile the latest d1x source release.  It's a game that has
been compiling just fine until the new rule about 'asm' in gcc 2.95.2.  I don't
think they will mind me posting a small portion of the code, so here's the part
that the compiler can't get past right now:

extern __inline__ void _farpokex (unsigned short selector, unsigned long offset,
void *x, int len)
{
  __asm__ __volatile__ ("pushl %%es\n"
                        "movw %w0, %%es\n"
                        "rep\n"
                        "movsb\n"
                        "popl %%es"
      :
      : "rm" (selector), "S" (x), "D" (offset), "c" (len)
      : "%ecx", "%edi", "%esi");
}


Does this make any sense to you (anyone)?  I don't really know any assembly so I
don't know what's wrong or what would possibly need to be changed.  I hope this
helps a little bit more.  Just to let you know, line number 13 (the compiler
error) is the line that goes: 

: "rm" (selector),...

If thats still not enough info (I'm notorious for this) plz let me know what
else you might need.  Just keep in mind that this isn't my code.  If anyone can
think of a way to fix this please let me know the method that you use to fix it
so that I can try to fix all the rest of the 'asm' problems in the code.  Thanks
again for your time and your input.
