Re: Hurd's configure.in
libc's aclocal.m4 has macros that appear to have the same intent as the one
in the hurd's aclocal.m4 (I'm not entirely clear on what the point of these
actually is). Can you try replacing your hurd aclocal.m4 with the
following, and changing hurd_PROC_CC -> AC_PROG_CC_LOCAL in configure.in,
and tell me whether that works with autoconf-2.50? If not, then libc will
have a problem too. Either way, we should have the same code for these
macros in libc and in hurd (gnumach has them too).
dnl These modifications are to allow for an empty cross compiler tree.
dnl In the situation that cross-linking is impossible, the variable
dnl `cross_linkable' will be substituted with "yes".
dnl The vercheck macros are expected to have been called already.
