Sure, now I get two different warnings:

  CC       ftfont.o
ftfont.c:2804:1: warning: ‘get_hb_unicode_funcs’ defined but not used
[-Wunused-function]
 get_hb_unicode_funcs (void)
 ^~~~~~~~~~~~~~~~~~~~
ftfont.c:482:1: warning: ‘ftfont_get_hb_font’ defined but not used
[-Wunused-function]
 ftfont_get_hb_font (struct ftfont_info *ftfont_info)
 ^~~~~~~~~~~~~~~~~~
