It was breaking the build on Windows. The problem was that we included
stdio.h which gave a prototype for some functions (e.g. remove), then
the AC_C_CONST meant that we did
/* Define to empty if `const' does not conform to ANSI C. */
#define const /**/
and then we included io.h which gave prototypes that, due to const
being removed, conflicted with the earlier prototypes.
# do we have long longs?
AC_CHECK_TYPES([long long])
# do we have long longs?
