[GENERAL] Undefined symbols: _poll

[Joe Lester]

I'm just moved my Postgres client project from Mac 10.2.8 to 10.3.5. 
It's an Objective-C program that links to libpq.a (the header file is 
libpq-fe.h). However, when I try to compile now I get the following 
linking error:

ld: Undefined symbols: _poll
Does this sound familiar to anyone? My guess is that _poll is 
referenced somewhere in libpq.a. Anyone have any ideas on how to get 
the linking happening on Mac OS 10.3.5?

Thanks!
Joe
