[PATCH 1/1] define memdup() static

[Hagen Paul Pfeifer <hagen-GvnIQ6b/HdU@public.gmane.org>]

memdup() is only referenced from dwarves.c. This patch defines them
static. Further symbol hiding can be accomplished via GCC attributes:

#if __GNUC__ > 3 || (__GNUC__ == 3 && __GNUC_MINOR__ >= 4)
# define DWARVES_NO_EXPORT __attribute__((visibility("hidden")))
#else
# define DWARVES_NO_EXPORT
#endif
