Hi,

It depends also a lot on the code packaging. For instance if the GPLed
library is packaged as a shared library on Unix or as a dll on Windows then
you can link to it because it won't be part of the code you provide but will
exist as a separate entity. Subtle but important ;-)

My understanding is, if you use GPL source without GPLing your code, you are
in violation of the license. You can, however, use a GPL'd program, provided
you don't link to it, and you provide the source. It is the LGPL that allows
you to link to the library. I am not aware of any way to use GPL'd source
without GPLing your own source, save not releasing at all.

If this is true, then my understanding is wrong.
