Basically, you need to take a look at the asm output.  It's automatiacally
made (be_callc.s) during the build.  If you look in the c code, you'll see
this line:

  arg = arg+argsize+9999; // just a marker for asm code

This is there basically to help you find the critical spot, and to figure 
out what the correct values should be.  At the top of the file, you'll see
these values for gcc 4.1.2:

#define push() asm("pushl -124(%ebp)")
#define  pop() asm( "addl -128(%ebp), %esp")

You're looking for something similar.  The gcc devs like to change this
stuff a lot (Watcom has been more stable).  There's some information in
readme.txt in the source directory.  If you're still having trouble, email
me the file, and I'll take a look at it.
