When trying to compile the attached preprocessed files using
gcc -c -fwhole-program --combine xterm.i xlwmenu.i
These warnings are produced unconditionally:
/home/dann/build/Emacs-CVS/emacs/lwlib/xlwmenu.c:57: warning: prototype for
'x_alloc_nearest_color_for_widget' follows non-prototype definition
/home/dann/build/Emacs-CVS/emacs/lwlib/xlwmenu.c:58: warning: prototype for
'x_alloc_lighter_color_for_widget' follows non-prototype definition
/home/dann/build/Emacs-CVS/emacs/lwlib/xlwmenu.c:64: warning: prototype for
'x_clear_errors' follows non-prototype definition
/home/dann/build/Emacs-CVS/emacs/lwlib/xlwmenu.c:65: warning: prototype for
'x_copy_dpy_color' follows non-prototype definition
AFAICT the warnings don't make much sense. The code is correct. The functions in
questions are defined in one file and then prototyped and used in the other
file. This kind of stuff appears in countless C programs.
Can this warning be turned off by default?
