I wasn't looking at the caller (and I haven't).  I agree that, if
you have to compare case-insensitive user input against known set of
tokens, using strcasecmp() would be saner than making a downcased
copy and the set of known tokens.  I do not know however you want to
compare in a case-insensitive way in your application, though.
