'Configure' finds uintptr_t by testing the following conftest.c.

  #line 4576 "configure"
  #include "xxxconfdefs.h"
  #include <stdio.h>
  #include <sys/types.h>
  #include <sys/stat.h>
  #if STDC_HEADERS
  # include <stdlib.h>
  # include <stddef.h>
  #else
  # if HAVE_STDLIB_H
  #  include <stdlib.h>
  # endif
  #endif
  #if HAVE_STRING_H
  # if !STDC_HEADERS && HAVE_MEMORY_H
  #  include <memory.h>
  # endif
  # include <string.h>
  #else
  # if HAVE_STRINGS_H
  #  include <strings.h>
  # endif
  #endif
  #if HAVE_INTTYPES_H
  # include <inttypes.h>
  #endif
  #if HAVE_UNISTD_H
  # include <unistd.h>
  #endif
  int
  main ()
  {
  if ((uintptr_t *) 0)
    return 0;
  if (sizeof (uintptr_t))
    return 0;
    ;
    return 0;
  }

A direct reason is that tags.h doesn't include all the headers
included in that conftest.c?  I have no idea how this should be fixed
properly though.
