C Expression Operands in asm instructions

["Dennis Tubbs" <dehotu at hotmail dot com>]

I am compiling a C program for the Motorola 68040 and am having a little 
trouble creating a macro which has assembler instructions with C expression 
operands.  I have read the section "Assembler Instructions with C Expression 
Operands" in the "Extensions to the C Language Family" manual but I am not 
all that skilled in compiler technology.

The macro I have created is:

#define BugSystemCall(x)   asm("TRAP #15; DC.W %0"::"n" (x))

The use of the macro is:

BugSystemCall(99);

The the compiler output is:

#APP
	TRAP #15; DC.W #99
#NO_APP

The problem with this is the assembler does not like the '#' in front of the 
99 and I don't know how to get rid of it.  If I hard code the macro to be 
asm("TRAP #15; DC.W 99") there is no problem.

I have tried every operand constraint that seemed like it might apply but no 
luck.

This seems like it ought to be rather simple but I am somehow missing it.  
Any ideas?

Thanks,
Dennis Tubbs
