setlocale and gettext in Postgres

Hi all,

I see now the following lines in libintl.h of version
0.18.1.1 which didn't exist in 0.17 version.

/* Support for the locale chosen by the user.  */
#if (defined __APPLE__ && defined __MACH__) || defined _WIN32 || defined
__WIN32__ || defined __CYGWIN__

#undef setlocale
#define setlocale libintl_setlocale
extern char *setlocale (int, const char *);
.
.

The macro may cause a trouble especially on Windows.

Though libintl_setlocale() calls setlocale() internally,
what the Mingw version of libintl library calls is the one
in msvcrt.dll not in the libraries which main programs link.
Unfortunately locale-aware functions like printf() calls
in main programs would see "C" locales not the locales set
by libintl_setlocale().

Attached is a patch to disable the macro on Windows.

regards,
Hiroshi Inoue
