Hi once again,

Last time it was an audio library, this time it is a network library.

I need a cross-platform, GPL-compatible networking library. Ideally, it would be properly object-oriented. (I already wrapped IJG's jpeglib in an object wrapper for this project, I don't fancy wrapping another library.)

Cross-platform: Absolutely must work on
x86 Win32
(x86_64 Win64) (should be pretty much automatic given the others)
x86 Linux
x86_64 Linux
Mac OS X

Should work on *BSD and pretty much every CPU architecture.
