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