+Subject: [PATCH] Drop use of obsoleted autoconf AC_HEADER_STDC macro.  Fixes
+ #409
+
+Use of the STDC_HEADER pre-processor macro that the autoconf macro
+used to define has been removed.  Conditionalized code is now used
+unconditionally.  This should be fine as the macro checks for ANSI
+C, i.e. C89 (ISO C90), compliant headers.  We already require C99.
