EINTR, EAGAIN, EINPROGRESS, EDOULDBLOCK Compile warning

Hi there,

When i compile my program with live555 header files, compile warning is occurring.

I'm developing the application in MSVC-2010, it seems to groupsock/include/netcommon.h file is comflicted with msvc2010/include/errno.h.

Your consideration in this matter will be appreciated.

Regards,

A compiler warning is not necessarily a problem. (Sometimes it can just be an annoyance.)

How are those four macros - EINTR, EAGAIN, EINPROGRESS, EDOULDBLOCK - defined in your "msvc2010/include/errno.h" file?
