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.
