gcc 2.95 has two problems
1. It has the odd minor bug in it. Probably less than the earlier
compilers but the ones in the earlier compilers are not hit by
current code - because it works ...
2. Its a way better optimiser. In paticular with its alias handling
enabled it optimises stuff a lot of folks didnt anticipate. That
can cause some app problems and needs a lot of testing of apps
especially coverage testing which is hard.
The 2.2.x kernel has been bitten by #2. We don't think it has been bitted
by #1 although we arent totally sure. Its hard to catch all the cases. While
2.2.14 was believed correct even in 2.2.15pre10 someone found another
fix needed for compiling with gcc 2.95

We have a bcc already, but thats Bruce's C Compiler used for 8086 boot
blocks and can also btw build DOS .com files under linux ;)

There is only one non gcc Linux build, thats the linux 8086 stuff, its very
different and the compiler stuff was a nightmare..
