(Hurd people: this is about a configure error when cross-compiling glibc
with libpthread as an add-on.)

Actually libc=E2=80=99s configure doesn=E2=80=99t use the normal AC_CONFIG_=
SUBDIRS
mechanism, and instead runs add-on configure scripts by itself, without
arguments AFAICS.

(This is libpthread=E2=80=99s config.log, right?)

I don=E2=80=99t understand where those arguments come from.

Ideas?

Thanks,
Ludo=E2=80=99.
