[Freeciv-Dev] (PR#11931) fc__attribute bug when compiling with libintl

["Jason Short" <jdorje@xxxxxxxxxxxxxxxxxxxxx>]

<URL: http://bugs.freeciv.org/Ticket/Display.html?id=11931 >

When compiling with libintl (GNU's gettext library, not to be confused 
with the gettext library included in glibc) I run into some unusual 
problems.

log.h:61: warning: `libintl_printf' is an unrecognized format function type
In file included from fciconv.c:39:

The problem is that libintl.h contains (I have no idea why)

#undef fprintf
#define fprintf libintl_fprintf

while log.h (and many other places) use

void real_freelog(int level, const char *message, ...)
                   fc__attribute((format (printf, 2, 3)));

the "printf" inside the fc__attribute is changed to a libintl_fprintf, 
which makes the format attribute invalid.
