| % autoconf2.50
| configure.in:55: error: undefine: undefined: zsh-debug
| configure.in:55: the top level
|
| The offending construct is here.
|
| undefine([zsh-debug])dnl
| AC_ARG_ENABLE(zsh-debug,
| [ --enable-zsh-debug compile with debug code and debugger symbols],
| [if test x$enableval = xyes; then
| AC_DEFINE(DEBUG)
| fi])
This
| configure.in:55: error: undefine: undefined: zsh-debug
reads `there is an error declared by undefine: zsh-debug is
undefined'.
I agree the original `undefine' from M4 does not do that. I agree the
message should be
| configure.in:55: error: undefine: undefined macro: zsh-debug
But by experience I know we need to be stricter to catch asap bad
bugs, so I definitely prefer the 2.50 behavior. I'd use
ifdef(,,undefine()).
