Menubar gui

hi all,

i noticed there are a couple of options for libraries that provide
menubars (File, Edit, Help, etc) under SDL in plain C.

i have no experience in this – can someone make a suggestion for a
library to use for menubars? i’m using plain C and would prefer
something that compiles under windows as well as linux. but if that’s
not available, just compiling under linux is fine.
