I don't quite understand what you're asking, but I'll take a shot at it...

I'm assuming you mean "extern int wibble(void);" here (ie, this is the
main program file and the other file is the assembly source for wibble()).

My suggestion would be to assemble to wibble file to an object file (such
as "wibble.o". Then compile and link in one command:
gcc -O2 myprog.c wibble.o -o wibble.exe
Either that or use inline asm in a wibble.c file and let gcc compile both.
