Hey Mugsy:
Did you ever figure this out? I was browsing the comp.lang.c newsgroup FAQ
(ok, somebody needs a life :P), and found this:
Question 11.17
I'm trying to use the ANSI ``stringizing'' preprocessing operator `#' to
insert the value of a symbolic constant into a message, but it keeps
stringizing the macro's name rather than its value.
-----------------------------------------------------
You can use something like the following two-step procedure to force a macro
to be expanded as well as stringized:
#define Str(x) #x
#define Xstr(x) Str(x)
#define OP plus
char *opname = Xstr(OP);
This code sets opname to "plus" rather than "OP".
An equivalent circumlocution is necessary with the token-pasting operator ##
when the values (rather than the names) of two macros are to be
concatenated.

I think you were trying to get the preprocessor to expand and then
'stringize' your #define'd constant, passing it's value as the arg to your
func, which is what that code appears to do.
