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. :-)
