annotate src/os/win32/ngx_process_cycle.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.
