Description
-----------

when compiling gb.xml module got this error that are not present 3.9.0 release:

  CXX    gb_xml_la-main.lo
  CXX    gb_xml_la-utils.lo
utils.cpp: In function ‘void XML_Format(GB_VALUE*, char*&, size_t&)’:
utils.cpp:254: error: expected `)' before ‘PRId64’
utils.cpp:254: warning: spurious trailing ‘%’ in format
utils.cpp:254: warning: too many arguments for format
make[6]: *** [gb_xml_la-utils.lo] Error 1

this are tdue the las BUG FIX change in commit 7887 about the 32bit printf format bug:

-				fprintf(stderr, "error write: %ld\n", size);
+				fprintf(stderr, "error write: %" PRId64 "\n", size);


this happend when the compiler doesn't support inttypes.h properly, means some backports (like winbuntu 12.04 LTS) could not be possible! my backports does will not possible due this change

this line must be added:

#define __STDC_FORMAT_MACROS 1

and also include after the last the 

#include <inttypes.h>

here the patch:
