I am compiling inline assembly with DJGPP of the format:

__asm__ __volatile__(
"asm code"
: // output variables
: // input variables
: // slaughtered registers and/or memory
);

I have four procedures using this same format.  But one gives me an
error message that I can't figure out.

1    __asm__ __volatile__(
2    "asm code"
3    : 			    // no output variables
4    : "r" (SBPort)              // input variables
5    : "%eax", "%ecx", "%edx" ); // slaughtered registers and/or memory

Line 5 produces an error that reads:
      invalid 'asm' : operand number missing after %-letter

I'm lost.  What does this mean?????? I have done it four other times
without error messages.  This procedure is the second of the four that
have the same format.  I triple-checked the syntax of everything around
it!!

Please respond.  Thank you!
