When I build tinycc on Windows (both 32/64 bit).


I always get this warning:


../tcc.c:136:39: warning: passing argument 3 of 'spawnvp' from incompatible pointer type [-Wincompatible-pointer-types]

     int ret = spawnvp(P_NOWAIT, prog, (const char *const*)argv);


Looking a spawnvp documentation from Microsoft, I get:


This POSIX function is deprecated. Use the ISO C++ conformant spawnvp instead.


So I replaced spawnvp by _spawnvp and no more warning when using mingw32/64 gcc compilers.


Please Windows maintainer (if any), can you consider this very simple change?
