+ * lib/autoconf/c.m4 (AC_PROG_GCC_TRADITIONAL, AC_C_CONST):
+ (AC_C_VOLATILE):
+ Do not recommend via AN_FUNCTION, AN_IDENTIFIER, or AN_HEADER.
+ These macros are obsolescent and new applications shouldn't need them.
+ * lib/autoconf/functions.m4 (AC_FUNC_CLOSEDIR_VOID, AC_REPLACE_FNMATCH):
+ (AC_FUNC_GETLOADAVG, AC_FUNC_GETPGRP, AC_FUNC_MEMCMP):
+ (AC_FUNC_SELECT_ARGTYPES, AC_FUNC_SETPGRP, AC_FUNC_STAT, AC_FUNC_LSTAT):
+ (AC_FUNC_STRFTIME, AC_FUNC_SETVBUF_REVERSED, AC_FUNC_UTIME_NULL):
+ (AC_FUNC_VPRINTF): Likewise.
+ * lib/autoconf/headers.m4 (AC_HEADER_DIRENT, AC_HEADER_STAT):
+ (AC_HEADER_STDC, AC_HEADER_SYS_WAIT, AC_HEADER_TIME): Likewise.
+ * lib/autoconf/types.m4 (AC_STRUCT_TM): Likewise.
+
* doc/autoconf.texi (Setting Output Variables): Mention that
@VAR1@VAR2 has unspecified behavior. Problem reported by
Ralf Wildenhues.
