I see a surprising number of cases where people use AC_CHECK_SIZEOF() on 'char', 'unsigned char', or 'signed char'. As all of these types are size 1 by definition, checking their size is unnecessary, bordering on cargo-cult programming. Would it be possible for autoconf to notice when AC_CHECK_SIZEOF has been applied to one of these types and issue a warning? (during the invocation of 'autoconf' itself, not during the execution of the configure script.) Suggested wording: configure.ac:NNN: warning: sizeof(char) is always one zw _______________________________________________ Autoconf mailing list Autoconf@xxxxxxx http://lists.gnu.org/mailman/listinfo/autoconf
