Well, yeah, but iodbc-config returning "-L/usr/lib" screws that up.
What's your point?

Looking closer at configure.ac, we actually have a similar issue with
pg_config. If you had libpq in the standard location, in /usr/lib/, and
libiodbc in a non-standard location, with your patch that case would go
wrong. No matter which way you order the -L's, it's going to be wrong in
the other direction. The solution is to not include standard paths like
/usr/lib in the output.

Perhaps it would be better to not use odbc_config / pg_config at all, at
least if the ./configure option is just "--with-libpq" and not
"--with-libpq=<path>". We could add just -lodbcinst and -lpq to LDFLAGS
directly, and assume that the required headers and libraries are in the
default system paths, without any -L or -I options. With that, you could
do "--with-iodbc" without a path and "--with-libpq=<PATH>", and it would
work, I think. Want to try writing a patch for that?
