It was a CVS snapshot some 18 months ago. Eighteen months of bug hunting
later you can tell nothing about its stability. In fact because Gcc 2.96 was
frozen
over a year before gcc 3.0 and has been far more dceployed I trust it far m
ore than gcc 3.0+
True, but I gather 3.0+ will pop up in a lot more distributions then just
redhat and mandrake.
3.0 is a official release which means it is not distribution specific. The
reason that mandrake adopted is was more or less because a lot of mandrake
is still redhat based. (no flame intended)
The gcc people are working hard on getting 3.0 stable. Most kernel
developers I met only work with official compilers. Not with wat shipped
with their distro.

Gcc 2.96 requires C++ functions being declared before their use. I have
found
many programs who need to be fixed.
The same for gcc-3.0

The only gcc tested by kernel people are egcs and gcc 2.95. There is ever a
danger kernel
will break if compiled with a different compiler. On another hand gcc
2.96 has
been used in
the two most popular Linux distributions so is a good test bench.
Expect more reports of 3.0 when that turns up in a new distribution.

AFAIK kgscc is no longer shipped with 7.1.
[seth@stimpy /data]$ which kgcc
/usr/bin/kgcc
[seth@stimpy /data]$ cat /etc/redhat-release
Red Hat Linux release 7.1 (Seawolf)
[seth@stimpy /data]$ rpm -ql compat-egcs|grep kgcc
/usr/bin/kgcc
[seth@stimpy /data]$
Reason kgcc was in 7.0 was because
gcc 2.96 did not compile kernel 2.2. gcc 2.96 had its bugs but in that
case it
was due
to broken code in kernel that old more tolerant compilers accepted but
should not
have.
kernel 2.4 has no longer this problem.
It's called compat-egcs for exactly that reason. It is a compatibility
package including libs to compile packages for redhat 6.2 environments.

2.96
genrates faster code than egcs but if you are wary of it the above is the best
solution

Every program has two purposes one for which

I use the last kind.
