So this breaks Raspberry Pi4 LinuxCNC? Any of the other 32 bit processors running LinuxCNC?
No, the OS or CPU has nothing to do with this change. These are 64-bit types in C/C++ that are used. It is not a CPU problem (but it helps the memory bandwidth utilization if the CPU has a wider bit-width).
That said, the RPi4 is fully capable to run a 64-bit Linux version too. Even the RPi3 has a 64-bit CPU and runs 64-bit Linux just fine.
The powerful x86/ARM CPUs that are exclusively 32-bit are extremely rare today. The 64-bit x86 extensions are publicly available in the AMD Opteron CPU since 2003 (!) and you can't get a new PC or RPi that has a pure 32-bit CPU today. Actually, compiling/running even today's LCNC would probably fail on an ancient purely 32-bit CPU.
I think the whole 32-bit CPU issue/discussion is moot with over two decades of 64-bit CPUs. Don't you agree?
