Your dates are slightly off. These gcc 1.x versions were between
1987 - 1993. I do remember using 2.7.2.3 with Linux 2.0 in 1997.

 
I'd agree that gcc main line release would be around 2.7 in 1998. I
can remember I started writing software for a Strongarm based video
security system in 2001. By then ARM kernels were compiled/cross-
compiled with gcc 2.95.x. Then gcc 3.0 / 3.1 came out which was
better for userland code but kernels compiled with it would not run
so we stayed with 2.95  for some time.

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 :-)

However, the SHARC stuff was definitely derived from gcc 1.x in 1998
as it struck me as very old as 2.x had been out for a while by then. 
This was the version of the compiler that ran on Windows. ISTR I used
a PII 200MHz probably running WinNT to develop on. The Unix systems
were reserved for ADA, Occam and other esoteric stuff ;-)

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.
