Greetings.
Please find attached a patch to GLIBC that is compatible with
the new version of binutils (HJLu's and CVS at least). I have
also added some cruft in 'configure.in' that will produce
warning messages if a user attempt to use old binutils. Comments
are welcome. I have gone out on a limb and also included a
Changelog entry in case this patch actually gets accepted :).
This patch will apply against the CVS version of GLIBC. Please
regenerate 'configure'. Thanks.
-Steve
***** Changelog entry *****
* sysdeps/mips/rtld-ldscript.in: removed unneeded binary
output format directive
* configure.in: added in checking for obsolete binutils
for MIPS targets which produces a warning message if
user attempts to use older tools.
