Both patches look a bit off to me, since argp should be usable in
multithreaded code. (This is a problem with the current gnulib, too,
but we should fix it while we're in the neighborhood.)
Instead, shouldn't we split gl_FUNC_GLIBC_UNLOCKED_IO into two pieces?
The first piece defines USE_UNLOCKED_IO and AC_LIBSOURCES
unlocked-io.h, and is useful only in non-multithreaded apps. The 2nd
piece requires gl_USE_SYSTEM_EXTENSIONS and checks for the
declarations of clearerr_unlocked, etc. The 1st piece depends on the
2nd piece. Argp depends only on the 2nd piece.
We could call the 2nd piece a new module "unlocked-decls", say.
