downgrading gcc, gentoo
 

is there a way to downgrade gcc, the current is 3.4, which is terrible, i want gcc 2.95, i want to know if there is a way to downgrade it with emerge, or if I have to do it from source

The current stable version seems to be 3.3.3-r6, which is probably the way to go. I have heard very bad things about gcc 2.x and I don't think gentoo supports it (its marked unstable, anyway). If you really want to install 2.95, try
however, I would recommend
to downgrade to the latest stable version.

here is a quote from the Linux from Scratch people......they were talking about gcc 2.95.........so
why would gentoo not support a GCC version with absolute stability???

I certainly wouldn't know--I only use it. But 2.95 is marked unstable, and I have had problems before while installing unstable development packages. I am certainly not an expert on compilers, but I'm pretty sure I've read rants about gcc 2.x before. Not that that's a great way to judge a piece of software, but still...

You could always compile it yourself or grab a binary package from somewhere. However, I'm not sure I see the point. The kernel developers say that gcc3.3 works to compile the kernel, but that it might not be suitable for production environments. But if you're running a server or something you'd probably be better of with RHEL or debian or something. Although I like gentoo a lot, stability doesn't seem to be one of its main goals.

It's probably in unstable because some of the new ebuilds might use compile options that are not available with the 2.x series of gcc which then might lead to ebuilds not working ok.
