Re: question on gp2c-run results

[American Citizen <website.reader3@gmail.com>]

I rebuilt using gpc version 0.0.14 instead of the older 0.0.13, and I 
symbolically linked in the pari v2.18.1 pari.cfg file as the INSTALL 
asks as the very first thing to do

Then gp2c-run test-polred.gp ran just fine, no exceptions noted

It would be very nice to have the -v option for gp2c-run working, so one 
can check the version.

This -v option works just fine for gp2c by itself.

For example the -h option works fine for both gp2c and gp2c-run.

Thank you.
