If this is where your egcs compiler is installed, yes. Please do this.
Then, assuming g++ points to egcs, you should see something like:

% g++ --version
egcs-2.92.34

This just means that you are going to have a separate install directory
for your v3 library binaries and library headers. This is what the
--prefix configure option does (you'll find this works the same on egcs or
other things like gtk+ as well)

The goal is to install the headers and libs in a separate place, other
than /usr/include (RH headers) or whatever /usr/local/* your are using for
egcs. . . . so that you can have all three on your system at once.

yup, just use -I and -L

? 
glibc is a different distro than egcs. I don't understand your question,
can you please provide more info?
