egcs installation questions

[Sean Chisek <riviera@famvid.com>]

hello.  i have a few questions about installing egcs.  i downloaded
the .tar.gz file of version 1.0.3 of egcs and untarred it and ran ./configure,
make and make install to install it.  one question i have is did i
need to do a make and a make install to install it?   it may
be a stupid question but i'm wondering if i need to keep all  the
directories that were made when i untarred it.  does the make install
just overwrite the old gcc/g++ files or do i need to keep all the other
directories so it has the library files?  also, is there a command
to type that will tell me if i'm running the gcc/g++ that came with my
linux or the gcc/g++ that is egcs?
