The change I made most definitely corrects the problem I was seeing where I
was getting no error handling in ecpg problems. I could correct my problem
by rebuilding only libecpg*. Sounds like the problem you found is related,
but not exactly the same as what I found.

Are you referring to the attachment threadsafe-libpq-742-diff.gz?
Unfortunately, I'm committed to 7.4.1 right now, so have to make it work
properly. threadsafe-libpq-742-diff.gz is rather large, and I don't think I
want to fit it into the 7.4.1 source. I can't just download the latest CVS
source. What can I change in my build to get it to properly specify
-D_REENTRANT? Sorry, I'm not a configure wiz...

The problem I found in config.status is definitely a bug. As released, the
build specifies '-pthread' on the GCC command line, which is obviously not a
valid GCC parameter. -lpthread needs to be specified, not -pthread.
