Well, I thought that was pretty much obvious we should, yes.

However, I've had a quick look, and it's not that easy... :-(

For example, regarding the issue we're actually trying to solve: the
check rsyslog's ./configure does is eventually using _isnan() which is
in -lm, but nothing in the NEEDED of libpq.so suggests -lm is needed,
not even in the dependency chain (i.e. NEEDEDs of NEEDEDs...)

So, I can have a deeper and longer look, but that will be later. Unless
Bernd beats me to it, that is. ;-)

Regards,
Yann E. MORIN.
