Hi!

A diff for executables?  That seems a very useful idea.  Maybe the
compiler experts in this list could help you with this task.

Please take a look at the Microsoft site, at
	http://www.microsoft.com

And issue two searches: one for "COFF" -- the new executable format, 
used in Windows NT and 9X. And the other for "PE", the old format, 
for Win16.

A good link is the documentation of the two formats:
	http://premium.microsoft.com/msdn/library/specs/f11/s9865.htm

You need to subscribe to this "premium" site, but this is free.

Microsoft web site is a good place to look for information about 
Win32 pgming.  Some would say: they created the mess, they must 
help solve it. :-)
