Hi, The description of the variable YACC is incorrect.
If you include AC_PROG_YACC in configure.ac and run the resulting configure script with --help, the output includes this description of the YACC variable: "The `Yet Another C Compiler' implementation to use." YACC actually stands for"Yet Another Compiler Compiler." The source file containing this error is programs.m4. It's a minor issue, but I think it's not just a cosmetic bug, because it might confuse someone into thinking that yacc is similar to or a replacement for gcc (which *is* a C compiler). Anyway, thanks for all your hard work on autoconf. - Chris
