Macs

AFAIK they decided to write the compiler entirely in FreeBASIC, so porting is an absolute bitch, even to something so similar to Linux or Windows like eComStation and OS X (if OS X uses the particular executable style used by FreeBASIC, which is from my guess either ELF or a.out, then it is plausible that it might be compatible with OS X). If they stayed with C it probably wouldn't be locked onto other platforms. I'd hate to try to write a port for an operating system that lacks a CLI like Mac OS Classic, so I think that one would be a real tossup.
