Why can't the windows version just be ported over? It's C/C++ afterall and that's what one of Linux's greatest strengths is: development of C/C++ code. Plus, as far as I know, it's not dependant on any Windows files. I'm sure porting would only be a minor job.
Uhh no? mIRC depends on probably THOUSANDS of Windows specific functions. Neither C nor C++ is completely portable. There are libraries available only for Windows. Porting mIRC to Linux would not only not be a minor job, it would be an incredibly complex and difficult job.
