[wmx] Compile Errors in WMX-6 with gcc 3.2 and intel C++

When I try to compile wmx-6 ( or patch level 1) under g++ version 3.2 I
get the following error:

c++ -c -g -O2 -I/usr/X11R6/include Menu.C
Menu.C:625: default argument given for parameter 3 of `
   CommandMenu::CommandMenu(WindowManager*, XEvent*, char* = 0)'
Menu.h:92: after previous specification in `
   CommandMenu::CommandMenu(WindowManager*, XEvent*, char* = 0)'
make: *** [Menu.o] Error 1

under intel C++, I get the following variant:

icc -c -g -O2 -I/usr/X11R6/include Menu.C
Menu.C
Menu.C(623): error: redefinition of default argument
  CommandMenu::CommandMenu(WindowManager *manager, XEvent *e,
  ^

compilation aborted for Menu.C (code 2)
make: *** [Menu.o] Error 2


Has anyone else seen this error before, and if so, does anyone else have
any suggestions about how to deal with it?

Thanks,
        Andy
