FWIW: I compile with PGI 7.1.4 regularly on RHEL4U4 and don't see

Thanks Jeff: it's good to know it's just me ;)

Following your message, I've tried building with PGI on a few systems:
Compiler OS Result
============ =================== ============
32-bit 7.1.6 CentOS 5.2 (32-bit) no threading
32-bit 7.1.4 CentOS 5.2 (32-bit) no threading **config.log
attached**
32-bit 7.1.4 RHEL4u6 (64-bit) works!
32-bit 7.1.4 CentOS 5.1 (64-bit) no threading
Each time it fails, it's because of "__builtin_expect" being
undefined for pgcc and pgf77 (works for pgcpp) - or any of the Sun
Studio compilers. Could this be a glibc 2.3 (RHEL4) vs. 2.5
(CentOS5) issue?
I'm afraid this one is out of my bailiwick -- I don't know. Looking
through your config.log file, it does look like this lack of
__builtin_expect is the killer. FWIW, here's my configure output when
I run with pgcc v7.1.4:
checking if C compiler and POSIX threads work as is... no
checking if C++ compiler and POSIX threads work as is... no
checking if C compiler and POSIX threads work with -Kthread... no

I suggest that you bring this issue up with PGI support; they're
fairly responsive on their web forums.
