error: 'O_BINARY' undeclared when compiling in Msys2 environment on Windows

[bardware]

Hi,

I checked this repo out in a msys2 environment under windows and call make. I eventually end up with the error

woff2sfnt.c:189:33: error: 'O_BINARY' undeclared (first use in this function)
         setmode(fileno(stdout), O_BINARY);

A quick search came up with this. Have you heard of this before?

Best,
Bernhard

To fix this add this piece of code to the top of woff2sfnt.c, below the last #include:

#ifdef WIN32
  #include <fcntl.h>
  #include <io.h>

  #if defined(_O_BINARY) && !defined(O_BINARY)
    #define O_BINARY _O_BINARY
    #define setmode  _setmode
    #define fileno   _fileno
  #endif
#endif
