Now, this I do definitely do remember. Stuck on 2.95.3 for years for
the kernel, whilst we were able to use newer compilers just for the
userspace. Linus kept running into code generation bugs and his rants
were gold! :-D

Also the great libc5 / glibc2 switch over which caused me a few
nightmares :-)

Yeah, that'd be right. Some people do keep old toolchains around
because it's the only way to build code for platforms that have gone
the way of the Dodo.
