*Reported by anonymous on 2001-12-10 11:09 UTC
When referring to an undeclared definition in a
complement expression no error is reported:

%%

r = !{s}

%%

will be accepted, but a NullPointerException is thrown
when the dfa is constructed as `s' is not defined.

I've reproduced the bug; macros containing complement or
upto are not checked for definedness before NFA
construction.

The bug will be fixed in the next release.
