Are you using linux & ncurses (isn't it)?
If so, the problem is not the typedef instruction in
src/sites/s.menu/include/menu.h (also if it is unusual)
but the confilct with the typedef for MENU in
/usr/include/ncurses/menu.h.

Solutions:
1 - Change the local name for include file menu.h (to Menu.h) and every
    file where it is used.
2 - Specify the local directory with include file menu.h to GCC.
    To do so you have to apply the follwing patch on file
    src/CMD/generic/make.mid and add the directive
    	 INCLUDE_CURSES = -I/usr/include/ncurses
    to your file src/CMD/head/linux
I hope this is useful for you - ciao, marco.
