Actually most if not all of those verb endings are used colloquially (the most important exception would be the second person plural, which is only used in some regions of Portugal).
2nd person singular is also never really used correctly, and even 1st person plural is sometimes replaced by 3rd person singular e.g. "a gente vai" instead of "nós vamos"
> most of the post IIWW ("classical") music that was composed in Europe is so unconnected to - not just wider audience - but what I'd call a physical aspect of music: pulse and resonance
On the contrary, pulse and resonance are two of the most intensively explored themes on post WW2 music!
Just two examples from the top of my head (among uncountable others...):
I didn't try Corman Lisp (I will), but it should be noted that sbcl works just fine in windows, despite a warning it used to carry about it being unstable. The difficulty of developing in windows, in my experience, has more to do with external things like ssl or sqlite, that may not be present in the system or may not be installed in the way that's expected by a lisp library, which wasn't as tested under windows.
What do you mean by 'fully'? I mean, with a lot of hard work, sweat, and cursing that comes with making any large game, not to mention a game engine and various support infrastructure too, there's at least one existence proof that they're at least 'working': https://kandria.com/ (How much cursing has been done at Windows vs SBCL vs OpenGL vs various libraries, only Shinmera knows. You might like a recent overview he wrote up of some of the development: https://reader.tymoon.eu/article/413 When things work well enough that "build with wine" is a viable strategy, that's pretty well in my book.)
A quick scan of the git page revealed references to Windows 2000, NT and XP (SP3 even!) but I didn't see mention of even Vista, nor anything newer.
A slightly longer look revealed an email from 2013 which seemed to speculate about the level of effort required to move to 64 bit support. So .. probably the short answer here is 'no'.
