There is intent to support these platforms, but as with every software 
that relies on volunteers, the actual extent varies. If you want to be 
sure that a platform is actively supported, check that the platform has 
an available and active build bot, because only this detects bitrot to a 
certain extent. If you want to be sure, create build and test systems 
for the systems you target yourself, you will then see if it works.

Yes, Linux 1 is obsolete and has been for > 10 years.

I'm not sure where these are used.

Mach is a microkernel. I'm not sure if the Mach C Threads interface is 
obsolete on Mach or if Mach overall isn't supported. Probably irrelevant 
for the desktop.

I think this is targetted at early Linux threads that used fork() while 
sharing most of the memory space. Obsolete.

Irix was a Unix variant shipped with SGI workstations. I don't kknow to 
what extent this is relevant for you. I think that the main use cases 
for these machines is 3D rendering/modelling, unless they have been 
superseeded by common desktop machines.

Just out of curiosity by one of your RTC users: What nice gimmics are 
you planning?
