                      (note - I am not subscribed to any relevent newsgroups)
To whom it may concern:

after installing gcc 3.1.1 (sucessfully with bootstrap, I sent in an email 
earlier for the Build Status page, copied below), I decided to install pgcc 
<URL:http://www.goof.com/pcg>, which is distributed via diffs to gcc 2.95.2.1.

I untargz'd gcc, ran the diffs, and ran configure with 
"--host=k6-pc-linux-gnu --program-prefix=p" as appropriate (seperate 
directory, etc).  This worked fine, no errors or warnings.  Ditto on make 
bootstrap.  Make install then proceeded to overwrite my new 3.1.1 binaries 
rather than make new ones with the specified prefix.

The directions on your website's faq for installing multiple copies of gcc at 
<URL:http://gcc.gnu.org/faq.html#multiple> say that this is okay (I specified 
an alternate host *before* the program-prefix, if this is the problem then 
that should be documented on the faq and configure --help).

Since there is a way to invoke the 3.1.1 compiler (via -V3.1.1), I see not 
much has been overwritten, but to save space, I have already blown away the 
source+compiled 3.1.1.

Is there a way to quickly re-create just the binaries so that they default 
back to 3.1.1 without recompiling everything? (and if not could that be 
considered for the next release?)

...and no, I'm not looking for "alias gcc='gcc -V3.1.1'" or a shell script or 
similar hack.

gcc -v:

Thank you for the time it took to read this message.

I have included the confirmation of build message (from before I messed with 
2.95.2.1/pgcc) below for completeness:
