Still being pretty new to GCC and having never used dejagnu, expect or 
Tcl, I'm trying to determine how to best integrate my test program into 
GCC's test harness.  I wrote this to help find breakages while working 
on optimizations for Microsoft 64-bit ABI pro/epilogues.  Rather than 
testing specific cases, it generates a few thousand unique tests by 
iterating through variations.  It consists of a C++ program that 
generates a pair of .c files (that I don't want in the same translation 
unit).  These are built along with a static .c and .S file and linked 
into the test program.  It is intended to be built and executed on the 
target machine and I currently run it manually with a frequently-edited 
Makefile.

The first thing I need help with is figuring out if this should be run 
by dejagnu or if I should just write a proper Makefile.in and add it to 
gcc's Makefile.in.  Integrating with dejagnu seems to be the most 
intuitive and simple, but I don't properly understand how this would 
affect a cross-compiler build.  Any advice?

Thanks!
Daniel
