Wes,
Did you try to ./configure w/out "--enable-thread-safety?" I recently
compiled postgreSQL 8.0.1 on Solaris and _needed_ --enable-thread-safety
strictly for building Slony-I against postgresql with that feature enabled.

What is the reason you are compiling this _with_ the feature?
If it's necessary, then you may need to --with-includes= and/or --with-libs=
with additional include directories, such as /usr/include:/usr/include/sys
where-ever the thread .h files are for your OS.

This configure attempt could be failing, because it can't locate the
correct thread headers and/or libraries

Why would I not want to specify enable-thread-safety? I want to be able to
write threaded programs.

--enable-thread-safety works fine until I enable --with-krb5, so it is
finding the thread libraries.
