@@ -146,6 +146,9 @@ GNU Autoconf NEWS - User visible changes. For compatibility’s sake, the C preprocessor macros STDC_HEADERS, HAVE_STDLIB_H, and HAVE_STRING_H are defined unconditionally. These preprocessor macros should be considered obsolescent. + However, cache variables like ac_cv_header_stdlib_h are not set; + this is intentional, so that AC_CHECK_HEADER([stdlib.h]) will still + do a test for the presence of stdlib.h, in case you genuinely need that. Future releases of Autoconf may reduce the set of headers checked for by AC_INCLUDES_DEFAULT. |
