I'm on a  FC 3 box using GCC version 3.4.4 20050721 (Red Hat 3.4.4-2).  I want to have GCC 2.95.3 at the same time  and don't want to disturb the current version of GCC.   I  downloaded the source,  simpily compiled with different --prefix options  and built with bootstrap options. But I failed to get it work.

Here are my steps

$ gunzip -dc gcc-everything-2.95.3.gz  |  tar -xvf -
$ mkdir gcc-2.95.3_obj
$ cd gcc-2.95.3_obj
$ ../gcc-2.95.3/configure --prefix=/usr/local/gcc-2.95.3
$ make bootstrap
$ make install

I  checked the GCC Frequently Asked Questions, and wanted to reinstall GCC 2.95.3 with new configuration again.

./configure --host=i686-redhat-linux --build=i686-redhat-linux --enable-multilib
--enable-shared --with-system-zlib --prefix=/usr  --enable-threads=posix --program-suffix=-2.95.3

make bootstrap

But I'm not sure it is correct for  above configurations and make options.   I have several questions,

1.  Did the first installation altered or modifyed my system?  Should I reintall GCC 3.4.4 with RPM package?
2.  Could anyone can give me some explanations for above configurations?
3.  What is the difference between 'make bootstrap'  and  'make' ?  Which one should I use?
4.  Is there another  better way to get gcc 3.4 and 2.95 at the same time without conflic?
 
Thanks
