Subject: localtime() calls work properly again on Alpha
Message-ID: <Pine.LNX.4.21.0004040941320.12710-100000@spawn.besmarter.com>

I've tested glibc 2.1.3-7 and the localtime() calls in the configure
scripts work properly again (I know fileutils had a problem with this
before). It appears that 2.1.3 finally fixed this long-standing bug.
