#ifndef Py_CONFIG_H
#define Py_CONFIG_H

/* pyconfig.h.  NOT Generated automatically by configure.

This is a manually maintained version used for the Watcom,
Borland and Microsoft Visual C++ compilers.  It is a
standard part of the Python distribution.

WINDOWS DEFINES:
The code specific to Windows should be wrapped around one of
the following #defines

MS_WIN64 - Code specific to the MS Win64 API
MS_WIN32 - Code specific to the MS Win32 (and Win64) API (obsolete, this covers all supported APIs)
MS_WINDOWS - Code specific to Windows, but all versions.
Py_ENABLE_SHARED - Code if the Python core is built as a DLL.

Also note that neither "_M_IX86" or "_MSC_VER" should be used for
any purpose other than "Windows Intel x86 specific" and "Microsoft
compiler specific".  Therefore, these should be very rare.


NOTE: The following symbols are deprecated:
NT, USE_DL_EXPORT, USE_DL_IMPORT, DL_EXPORT, DL_IMPORT
MS_CORE_DLL.

WIN32 is still required for the locale module.

/* Visual Studio 2005 introduces deprecation warnings for
   "insecure" and POSIX functions. The insecure functions should
   be replaced by *_s versions (according to Microsoft); the
   POSIX functions by _* versions (which, according to Microsoft,
   would be ISO C conforming). Neither renaming is feasible, so
   we just silence the warnings. */
