I used to build xchat for win32 packages; I stopped it more or less ’cause I sort of had to switch to irssi.
Nevertheless, here’s my last build for windows. It’s a bit outdated and I removed the SSL version:
X-Chat Package for Windows
This is the X-Chat package I compiled for win32. It has most features disabled (Perl, Python, TCL, SSL, MMX, NLS), because it was the easiest way to go. Plus there’s no nifty intaller.
If you need any of this, go to XChat for windows homepage and download and register the package you find there to help the development of this fine piece of software or grab another build listed here
You’ll also need a GTK 2.4+ Runtime package. (Try looking at gaim or gimp)
