Building R10B-3 on Mac OS X Tiger

[Bjorn Gustavsson]

Thanks for the workaround and the information.

However, the tech note is from Sep 2003.

poll() actually exists and works in Panther. It does seems to
exist in Tiger, too.

We'll try to fix the problem in OTP R10B-6 (it's too late for
R10B-5).


Regarding the workaround:

Instead of removing system header files, I suggest the following patch
to erts/configure. I have not actually tested it on Tiger, but it does
force the emulator to use select() instead of poll().
