This is the original rfc1459.c can you change it? because i dont know and i dont want to make something wrong :/ can you help me?

*
* This code was more or less cloned from the ircd-hybrid 5.3 source.
* The original code was written by Otto Harkoonen and even though it
* it not entirely in synch with section 2.2 of RFC1459 in that it
* additionally defines carat as an uppercase version of tilde, it's
* what is in the servers themselves so we're going with it this way.
*
* If for some reason someone who maintains the source for ircd decides
* to change the code to be completely RFC compliant, the change here
* would be absolutely miniscule.
*
* BTW, since carat characters are allowed in nicknames and tildes are
* not, I stronly suggest that people convert to uppercase when doing
* comparisons or creation of hash elements (which tcl laughably calls
* arrays) to avoid making entries with impossible nicknames in them.
