[fpc-devel] ARM/AARCH64 work

[J. Gareth Moreton]

I can't promise anything just yet, but I'll see what I can do.

At the moment I'm still learning to configure anything.  I've had apps crash from out of memory 
errors and the CPU get throttled due to overheating while trying to play a YouTube video.  I've got 
some things sorted by increasing the size of the swap file.  Frankly I want my laptop back so I can 
get a proper e-mail client again, since I can't quite remember the server details off-hand and the 
Webmail client causes problems with indenting in the fpc-devel mailing list, as you undoubtedly 
remember.

When you say Windows 10 on ARM64, do you mean an actual build for ARM processors or an x86_64 
version running inside a virtual machine?  Presumably I'll have to buy a copy of the OS for that, so 
it will have to wait for a little bit if that's the case.  But hey, I'm all for cross-platform 
development.
