Thank you for the tip with the -I option.

Hmm I’ve since destroyed the Parabola operating system and
switched to GuixSD.  It still happens when I run

$ guild compile-ffi -I /gnu/store/0jjgg2bk6qmx87sdksm7bd2b3z10yd6j-gettext-0.19.8.1/include -I /gnu/store/n6nvxlk2j8ysffjh3jphn1k5silnakh6-glibc-2.25/include gettext-po.ffi
ffi-help: WARNING: the FFI helper is experimental
(unknown):1: not found: "gnu/stubs-32.h"
compile-ffi: parse failed

A gnu/stubs-64.h exists though.

Apparently I need to install the 32-bit version of glibc in
order for it to work.  I tried

$ guix build -s i686-linux glibc
[…]
@ build-succeeded /gnu/store/g7fj77yfv1m4xilfqxvzggm5kd20i10z-glibc-2.25.drv -
/gnu/store/km57wad98gyghrbj8pwydcscsh9y4n4d-glibc-2.25-debug
/gnu/store/n0nvyn4lbcawfdbmd0blydrsp5wll75n-glibc-2.25

Now
$ guild compile-ffi -I /gnu/store/0jjgg2bk6qmx87sdksm7bd2b3z10yd6j-gettext-0.19.8.1/include -I /gnu/store/n0nvyn4lbcawfdbmd0blydrsp5wll75n-glibc-2.25/include gettext-po.ffi
ffi-help: WARNING: the FFI helper is experimental
wrote `gettext-po.scm'

worked with the original header file.

(

Removing /usr/bin/gcc leads to a
different error message:

$ guild compile-ffi gettext-po.scm
/bin/sh: gcc: command not found
[…]

)
