Change prefix to re-install

Change prefix to re-install

[Christopher R. Jones]

I compiled and installed egcs-1.1.2 on a Pentium Pro, Solaris 7.  I did not
use the default prefix as gcc was already installed in /usr/local .  Now is
looks like a lot of work to get the system to use egcs instead of gcc. What
is easier, changing prefix in the Makefile and using make install or
creating all the symbolic links?  

I used --prefix=/usr/local/egcs

My concern is getting the system to use the include files and libraries
created by egcs.

If you change the prefix you will need to rebuild -- just reinstalling will
not work.

I've done it both ways.  Using --prefix=/usr is more convienent over time
(since it overwrites the old crufty compiler).  But you should only do this
if you are comfortable completely replacing your system compiler.

Else you should use --prefix to install egcs into its own location.  You
can then make a symlink in /usr/bin to the various binaries like gcc, g++,
g77, etc etc.  This will work fine too.
