That will build a new compiler, but not install it.

"make install" will install the new compiler.

By default, egcs will install itself into /usr/local/...  You'll
need to see where your gcc-2.7 compiler is installed to determine
if it will be overwritten.

It's not possible to make a g77 only compiler...
