2.4.5 is one of the more stable versions of gcc (tried and true).  As a   
matter of fact, the standard precompiled gcc compilers for both Sun   
Solaris and SGI use 2.4.5.  Besides, there are several coding work   
arounds for the is-ums with 2.4.5 (so from what I've read)

Regardless, I have to agree, there is no reason a latter version could   
not be adopted that is just as stable and with bug fixes, no less.

Subject:  Why still using GCC 2.4.5?

I've been using FreeBSD on my PC for the last few weeks and loved
it so much that yesterday decided to try out NetBSD on my SPARCstation 2.
Right now I'm doing a "make build" on NetBSD-current and I noticed that
NetBSD is still using GCC 2.4.5?!?  Why hasn't it been upgraded to 2.7.0,   

or 2.6.3, or even 2.5.8?

At any rate, after it finishes installing /usr/lib, I'm going to try
compiling GCC 2.7.0 and then finish the build.  In the meantime, are
there any known problems with these later version of GCC (I know 2.6.3
has some optimizer bugs with -O2 on the i386), that have prevented
NetBSD-current from upgrading, or is it just simple inertia?  Thanks in
advance!
