Wed Jun 11 12:41:02 PDT 2003
Hi all,
the attached patch introduces replacement functions for inet_ntop and
inet_pton, taken from the ircii project, and published under a BSD license
without an advertising clause.
these replacement functions are needed on cygwin, and apparently on hpux.
cheers,
dalibor topic
