Added the typecheck.m4 macro file to improve type checking support in
the configure.ac script. The various typedefs are checked in a larger collection of locations.

+dnl We cannot use the AC_CHECK_TYPE macros becasue AC_CHECK_TYPE
+dnl #includes only <sys/types.h>, <stdlib.h>, and <stddef.h>.
+dnl Unfortunately, many implementations today hide typedefs in wierd
+dnl locations: Solaris 2.5.1 has uint8_t and uint32_t in <pthread.h>.
+dnl SunOS 4.1.x has int8_t in <sys/bittypes.h>.
+dnl So we define our own macro AC_UNP_CHECK_TYPE that does the same
+dnl #includes as "unp.h", and then looks for the typedef.
+dnl
+dnl This macro should be invoked after all the header checks have been
+dnl performed, since we #include "confdefs.h" below, and then use the
+dnl HAVE_foo_H values that is can #define.
