+http://sourceware.org/ml/libc-alpha/2007-03/msg00017.html:
+
+GCC trunk now has multiple internal headers directories, one
+containing the self-contained GCC-provided headers and one containing
+the <limits.h> (not self-contained but including libc's <limits.h> or
+a fixed version thereof) and the fixed headers; more such directories
+may be added in future.
+
+When glibc uses -nostdinc, it needs to use -isystem options for all
+these internal directories.  This patch teaches it about the
+include-fixed directory (and is harmless with old GCC versions without
+that directory).
+

+
+       * configure.in: Also pass -isystem option for GCC's include-fixed
+       directory.
+       * configure: Regenerate.
