#60 linking to pthread causes errors
Compiling evms-2.3.3 didn't work because of a problem
linking with libpthread.a. Complained that
pthread_atfork was undefined reference. Seems there is
only a reference to old_pthread_atfork in libpthread.a,
but there is a reference to pthread_atfork in
libpthread_nonshared.a. Fixed by adding
PTHREAD_LIBS = /usr/lib/libpthread_nonshared.a -lpthread
in make.rules. Not sure if it's distribution specific,
but downloading the glibc/linuxthreads source seems to
say that it's more to do with the default config for
compiling glibc. (?) Not sure if this is a bug, because
I didn't see any references in the mailing list, and
I'm not sure if this actually fixes anything or just
creates a potential error. I was also unable to find
anything in the documentation, though I could've
overlooked it. Hopefully, someone else will not have to
go through the same frustration to get evms to compile,
if this is indeed a quasi-bug.
glibc was version 2.3.2

I don't believe we've ever experience this problem while
building EVMS, and I don't believe this bug has been
reported before.
Please attach the output from "./configure" and "make" on
your system so we can see exactly where the build is
failing. Also, which architecture and distro are you using?

Sorry it's been so long. Here are the outputs of configure
&& make from evms-2.3.4. (NOTE: this is a newer version than
in previous post.)
Arch: x86 (amd smp: nothing out of the ordinary)
distro: Slackware 9.1
In summary, the build is failing at the link stage. The only
file that makes a reference to pthread_atfork that I could
find is "engine/engine.c". The build fails when linking
worker.o (engine/worker/worker.c) with libpthread and libevms.
I don't think there's a real "bug" in evms or in the
Slackware distro. As I mentioned previously, it looks like
something straight from glibc, which I don't claim to
understand, and Slackware, in general, doesn't do a lot of
customization of source.
I hope this
