Yves, there are a number of compilers on the market for windows which can
target mac, linux, windows and embarcadero is one of them. impossible is the
wrong word I think. it might be very difficult, but I can't see impossible. the
code base might have to change drastically though since the CRT and libraries
would be all different at least, only the host would stay the same (making it
practically a different GNU compiler almost). I hope I am not wrong.
it would be a cross compiler if I am not mistaken, and having something like
that would be wonderful (but a lot of work to maintain and make). cross
compilers have existed for decades.
I think vityan made a nice windows-hosted cross compiler targeting ubuntu and
freebsd. it was removed probably because of age.
apple has their XCode for apple developers, and I don't know what the license
agreement is for that, but I think they have a gcc included in that strangely
enough. maybe this is why it's impossible? it's a click license or something
probably.

After several weeks pulling my hair, I figured it might be a good
