Installer Problem WinNT to Win 98

[achrist at easystreet.com]

Some months ago I posted aquery about how an installer-generated
exe would run fine business on NT and crash on Win 98.  Tonight
I had opportunity to track down the cause:

    The library routine getpass.getuser() doesn't work on Win 98.

This works fine on NT, but raises an exception on Win 98, which
the program must catch and plug in a bogus user name, I guess. 

Anyone have a good list of such pitfalls between Windows versions?
