This doesn't make any sense, for two reasons:

1. How is render.c getting into the ctypesgen wrapper generation
process? ctypes generates a temporary .h file which #include's various
.h files. No .c files should be getting processed.

2. The error relates to an invalid __attribute__ qualifier.

2.1 These should be getting replaced by the empty string due to gis.h
and the fact that ctypesgen undefines __GNUC__:

	#if !defined __GNUC__ || __GNUC__ < 2
	#undef __attribute__
	#define __attribute__(x)
	#endif

2.2 Attribute qualifiers are dealt with by the compiler, but ctypesgen
only invokes the preprocessor.

If you're getting this error while compiling lib/nviz, the problem is
caused by:

	#include <grass/glocale.h>
	#include <grass/nviz.h>

<grass/gis.h> should be include *before* <grass/glocale.h>.

The reason is that glocale.h includes <libintl.h>, which #define's
printf to libintl_printf.

This affects the __attribute__((format(printf,...))) qualifiers,
causing the above error.
