+        Assume freestanding C89 headers, string.h, stdlib.h.
+        Again, this simplifies the code, and all current platforms have these.
+        * configure.in (AC_CHECK_HEADERS): Don't check for limits.h.
+        (AC_HEADER_STDC): Remove.
+        (AC_CHECK_FUNCS): No need to check for strchr, strrchr.
+        (strchr, strrchr): Remove fallback macros.
+
+        Assume support for memcmp, memcpy, memmove, memset.
+        This simplifies the code a bit.  All current platforms have these,
+        as they are required for C89.  If this turns into a problem we
+        can add the gnulib modules for these (a 1-line change to Makefile.in).
+        * configure.in: Don't check for memcmp, memcpy, memmove, memset.
