dnl We cannot use the AC_CHECK_TYPE macros because AC_CHECK_TYPE
dnl #includes only , , and .
dnl Unfortunately, many implementations today hide typedefs in wierd
dnl locations: Solaris 2.5.1 has uint8_t and uint32_t in .
dnl SunOS 4.1.x has int8_t in .
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 it can #define.
