GnuPG 1.4.0 vasprintf problem under WIN32

[Joe Vender]

Attempts to "make" GnuPG 1.4.0 under MinGW/MSYS as per instructions by Carlo Luciano Bianco at http://clbianco.altervista.org/gnupg/eng/gnupg.html (alternative compilation instructions as modified slightly from 1.2.6 instructions) fail and return the following error:

I'm not a programmer, but playing around, here's what I've tried. In strgutil.c, if I modify the source with the following:
****

 vasprintf (char **result, const char *format, va_list args)
 {



Then make succeeds. Make also succeeds if, using an unmodified strgutil.c, references to vasprintf are changed to libintl_vasprintf in ttyio.c:

I have no idea if either one of these is correct. I've found that vasprintf if defined extern in libintl.h, which is #included in i18n.h under WIN32 which is itself #included in bftest.c where this problem seems to occur.

The code references to vasprintf in libintl.h are:

#undef asprintf
#define asprintf libintl_asprintf
extern int asprintf (char **, const char *, ...);
#undef vasprintf
#define vasprintf libintl_vasprintf
extern int vasprintf (char **, const char *, va_list);


If anyone has any idea what's going on with this failure due to the vasprintf code when building under MinGW/MSYS as per instructions by Carlo Luciano Bianco at http://clbianco.altervista.org/gnupg/eng/gnupg.html , please post a solution.

Thanks.
