The files
 
 asnprintf.c 
 printf-args.c
 printf-args.h
 printf-parse.c
 printf-parse.h
 vasnprintf.c
 vasnprintf.h

are taken from the vasnprintf module of the GNUlib package, which can
be found at: 

 http://www.gnu.org/software/gnulib/

All files have been modified to include g-gnulib.h. 

vasnprintf.c has also been modified to include support for long long 
printing if the system printf doesn't. This code is protected by 
#ifndef HAVE_LONG_LONG_FORMAT.

Code has been added to printf-args.[ch], printf-parse.c and vasnprintf.c
to support printing of __int64 values with the I64 format modifier. This
is protected by #ifdef HAVE_INT64_AND_I64.

The files

 printf.h 
 printf.c
 g-gnulib.h

have been written by me. printf.[hc] contain implementations of the  
remaining functions in the printf family based on vasnprintf. 
g-gnulib.h is included by all source files in order to move all
exported functions to the _g_gnulib namespace, replace malloc by
g_malloc and make sure that snprintf is only used if it implements 
C99 return value semantics.
