[zeromq-dev] Cross-compiling zmq for PowerPC-405

Hi,

epoll() was introduced in Linux kernel 2.5.44 and glibc 2.3.2, all of which
are at least 5 years old today. You really should get an updated platform
SDK for your target board.

Try "make V=1" to turn off the silent build rules, and verify that
-DZMQ_FORCE_POLL is indeed being passed to the build for all C and C++
source files.

Mikko, Pieter, would it be worth backporting the --with-poller autoconf
stuff to 2.1.x to make this easier for people?
