Re: comiling error in exec

[Alfred M. Szmidt]

   Honestly, I would prefer that we just require pretty darn new libc
   for use with hurd.  But if that is really an imposition, using
   #ifdef is fine for this.  There is no great loss in just disabling
   the new functionality.

I don't see any problems with this, the Hurd and glibc are quite
tightly linked in more ways then one.  What one can do is to add a
config check to autoconf that will barf if you try to compile the Hurd
with a older glibc.  And then maybe have a --enable-old-glibc switch
to override it.  This would also clean up a bit in
[hurd]/configure.in.

Not sure how one would detect the version of glibc in a sane manner
though.  __GLIBC_PREREQ only cares about major and minor versions; we
would need some kind of a mini-version check.

Anyway, what do you think about doing something like that?

Cheers.
