I looked in the GSL "help" mailing list archives, too, and saw that people were being referred to this list. The gsl configuration script rings a bell, though. > At least the Debian packages contains an M4 macro (gsl.m4) written by > the GNU Scientific Library project. Did you check it out?

I can probably find a copy of the macro somewhere and try it. However, I would still be interested to know if there's a way of passing specific options to the C or C++ compiler when `configure' runs its tests without having to go deeply into the guts of Autoconf. I have looked into it a bit, but it seems like a major undertaking to really understand how to use it at that level. Thanks again for your help.
