yeah, i didn't notice that this declaration was in the #else
conditional. i should have used this instead:

i was getting errors:

because typedefs in libs/luafontforge/fontforge/inc/basics.h
were clashing with typedefs in system header <sys/inttypes.h>

 TH> src/texk/web2c/luatexdir/font/luafont.c: one of the new "halfword

thanks for looking at this.

Best,
