possibly.  On UnixWare, the original executable in the process needs to 
have -K[p]thread
specified to get libthread included.  I'll be adding -D_REENTRANT to the 
libpq build for
UnixWare to make sure that libpq is threadsafe, but doesn't include the 
thread library as
a pre-requisite per input from SCO.

BTW, Bruce, SCO OpenServer does NOT have threads.
