Hello all,

I'm using MinGW 4.2.1 and was unable to compile my code when including
pyconfig.h.

The culpables are these lines (from line 428):

/* Define to `int' if <sys/types.h> doesn't define.  */
#if 1 //_MSC_VER + 0 >= 1300
/* VC.NET typedefs socklen_t in ws2tcpip.h. */
#else
#define socklen_t int
#endif

MinGW (at least the version I use) typedefs socklen_t too, in ws2tcpip.h
(at line 272):
typedef int socklen_t;

When the #define takes effect, code becomes:
typedef socklen_t socklen_t;

...which leads to a compile error (really hard to understand):
C:/MinGW/include/ws2tcpip.h:272: error: multiple types in one declaration


I hope these details will be useful for you. I'm available for another
questions.

Thanks!

Sorry.

This block is only to support the older VC6 compiler. Since your
installation was most certainly compiled with VS7, your change is correct.

(or better, something like:
   #if !defined(_MSC_VER) || _MSC_VER + 0 >= 1300
)

The trunk version (future 2.6) was already fixed with r64214: the
"#define socklen_t int" was moved to socketmodule.h, which is not
included in python.h.
