mozilla build problem with current libc cvs?

[Jack Howarth]

   Has anyone tried rebuilding mozilla 0.8 against the most current
libc cvs? I am seeing a build failure with the redhat mozilla-0.8-2
srpm which didn't happen a few weeks ago....

/usr/src/redhat/BUILD/mozilla /usr/src/redhat/BUILD/mozilla
+ cd /var/tmp/mozilla-root//usr/lib/mozilla
++ pwd
+ LD_LIBRARY_PATH=/var/tmp/mozilla-root/usr/lib/mozilla
++ pwd
+ MOZILLA_FIVE_HOME=/var/tmp/mozilla-root/usr/lib/mozilla
+ ./regxpcom
./regxpcom: error while loading shared libraries: /var/tmp/mozilla-root/usr/lib/mozilla/libnspr4.so: undefined symbol: fstat

Has there been any changes to fstat that would cause this and is
anyone else seeing this on platforms other than ppc?
