The best thing would to let the wxWidgets people change the behavior of wxWidgets to let it be the same in Windows as in Linux. You could write a ticket for this[0]. To be sure this problems isn't forgotten, you should also write a wxHaskell ticket[1], preferably linking to the wxWidgets ticket. The message about the unexpected parameter stems from wxWidgets\src\common\cmdline.cpp , method wxCmdLineParser::Parse(bool showUsage) . Maybe it is possible to specify a wxCmdLineParser, that handles the +RTS parameters correctly, in wxHaskell.
