The best suggestion so far would seem to be from druck: write the module
that will contain the assembler as a prototype and an empty C function:

/* Prototype, put in a header file, myfunction.h  */
int myfunction(int, char*);

/* empty function as the only contents of a source file, myfunction.c */
int myFn(int bufflth, char* buff)
{
  return 0;
}

include a recipe for this module in your Makefile, compile it and then,
when you know it all compiles and links OK, either
(a) fill the myfunction() body with inline assembler statements
or
(b) grab the assembler source file that gcc produces from it, insert
your assembler code in that and modify the Makefile recipe accordingly.

I'd go with (a) but YMMV.
