winpdb seems to be looking for an environment variable (APPDATA) that is not supported on Win 98. As a workaround you could replace line 606 in C:\Python24\Lib\site-packages\winpdb.py which says
        if os.name == 'nt':
        if os.name == 'nt' and os.environ.has_key('APPDATA'):

This will make winpdb create its settings file in the current directory with the name winpdb_settings.cfg.

Reporting this as a bug on SourceForge is also a good idea.
