wxWidgets/src/unix/gsocket.c
Guilhem Lavaux aa6d970619 Updated wxSocket documentation 
Renamed GSOCK_TIMEOUT to GSOCK_TIMEDOUT
Added wxURL::ConvertFromURI
Use wxUSE_LIBGIF in imaggif.cpp and samples/html/test/test.cpp
Full implementation of "timeout"s in gsocket.c
Non-blocking WaitConnection()/Connect() are supported now.
