Hi,

[Sent here from #emacs - please CC me on any replies]

After configuring with:

 ./configure --prefix=/home/martin/emacs --with-freetype
--with-xft --enable-font-backend --with-gtk

I was getting the following error building emacs-unicode-2
on AMD64, although the same code
compiled fine on a 32 bit machine:

martinearthworm:~/emacs/emacs/src$ gcc -c -D_BSD_SOURCE

font.c: In function ‘Fget_font_glyphs’:

After adding a function prototype it builds and appears to
run fine:

    font.c:2671: error: conflicting types for ?Flist_fonts?
    font.c:2523: error: previous implicit declaration of
?Flist_fonts? was here
    font.c: In function ?Ffont_fill_gstring?:

Please investigate what the two conflicting types are.
That is the first step towards fixing the bug.

Thank you for the report.   I've just installed this change
