#5 stdint.h should not be included if unavailable

[Mike Henderson]

The configure script detects that the header file
<stdint.h> is not available and properly notes that
in the config.h file but the src/ferite_scanner.c
file still includes it.

System - SunOS 5.8 with gcc-4.0.2 and ferite 1.0.2

config.h:
/* Define to 1 if you have the <stdint.h> header
file. */
/* #undef HAVE_STDINT_H */

src/ferite_scanner.c:
#include <stdint.h>
