I am afraid you're violating GPL this way. It doesn't matter if you
distribute this lib or not. The fact is that you use lib's headers
and use lib itself (while compiling and then linking the program).

You could say so if you could compile FireBird having NO libreadline
on disk (for ex. with some stub lib only and own headers).
But you can't (ATM).

Even then (if you could) - the user using such FireBird would be
violating GPL, as he would effectively link GPL-incompatible program
to GPLed library (he won't be able and/or will not want to use empty,
stub lib).

To call it simple - that way or another - it's illegal.
Maybe FSF would not sue you (however I would not be so sure ;-) nor
the user, but this is ethicaly wrong.

IANAL (that's why I am Cc:ing d-l in case I were wrong somewhere)

That's all what's needed.

Thank you for your understanding
