hi,

How can i get the below code working without the need of the Cygwin?
i also hoop that the exe size can be a bit smaller, it is now 300K
I tried to include <windows.h> <windows32\sockets.h> and drop the sys/socket and netinet/in
because those files generates many errors with -mno-cygwin option.
gcced with : gcc -mno-cygwin -lwsock32 test.c
i think that if you don't use cygwin you must use winsock it self am i right?
so the -lwsock32 is neccesary?

thx for you support.
