Hi Stephane,

 well, my humble suggestion would be that you only use
- -L/house/bortz/lib conftest.c -lpopt when needed. On our recent
"configure.ac" we did as follows (in a m4 macro):

 - save a copy of LIBS, CFLAGS, LDFLAGS (and so on),
 - check for any library (popt in your case), check if it works, and
store the directories and files in their  proper popt_LIBS,
popt_LDFLAGS, popt_INCLUDES  (and so on),
 - store the original LIBS, CFLAGS, LDFLAGS...

 This will lead you to use these popt_* values in your Makefile.am and
let your compile environment clean when running configure.

Regards,
