nginx: src/event/modules/ngx_win32_select

annotate src/event/modules/ngx_win32_select_module.c @ 5360:3d2d3e1cf427

Win32: MinGW GCC compatibility. Several warnings silenced, notably (ngx_socket_t) -1 is now checked on socket operations instead of -1, as ngx_socket_t is unsigned on win32 and gcc complains on comparison. With this patch, it's now possible to compile nginx using mingw gcc, with options we normally compile on win32.
