Guix targets glibc-based systems, so as you write, it=E2=80=99s reasonable = to assume argp is present. Also, using AC_CHECK_HEADERS doesn=E2=80=99t achieve anything: it only defi= nes =E2=80=98HAVE_ARGP_H=E2=80=99 to zero or one. Last, I don=E2=80=99t want to discourage anyone from porting, but I also wa= nt to be clear about what it entails. I=E2=80=99m strongly in favor of supporting only glibc because: (1) after all, it=E2=80=99s about GNU as a system, and = (2) my experience with Nixpkgs is that supporting multiple C libraries is just too much work to maintain good support. Thus I=E2=80=99m closing for now. Thanks, Ludo=E2=80=99.
