New programs need not use this macro". Was previously required to ensure the system has C header files conforming to ANSI C89 (ISO C90). Specifically, this macro checks for stdlib.h, stdarg.h, string.h, and float.h. This autoconf option was used to provide conditional fallback support via defined STDC_HEADERS. valgrind does not utilize conditional fallback support so, so this macro is both obsolete and unused, so let's drop it.
