Re: [Tinycc-devel] spawnvp V.S. _spawnvp on Windows

Hello Christian,

That was an annoying warning. You patch works for me on my flavors of Windows on the toolchain provided by Strawberry Perl. Thanks!

Subject: [Tinycc-devel] spawnvp V.S. _spawnvp on Windows

 

Hi,

 

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?

 

Christian
