[Mingw-users] Minor patch for winsock/winsock2

[Michael G. <mg...@te...>]

Hi list !

I have come across an untidyness in the definition of FD_SET as
can be found in winsock.h and winsock2.h.

In the macro FD_SET is a comparison between the member u_int fd_count
of the structure fd_set and the constant FD_SETSIZE which is signed.

This results in an warning "comparision between signed unsigned".

I therefor propose to either
- change the definition of FD_SETSIZE from '64' to '64u', or
- add a cast (u_int) to the comparison in FD_SET

The later is local to the macro and should have no impact on any
existing program while the former might have effects on other
programs which use FD_SETSIZE.

While I'd prefer the former change, the later probably is the more
conservative solution and thus to be preferred.

Such change would have to be applied to both winsock.h and winsock2.h.

Best,
Michael
