Neither are good. GPL is mostly definitely not allowed for library routines
(it is fine for the compiler, IDE or utils)

LGPL-with-linking-exception to be precise. (see rtl/copying.fpc for the
differences with ordinary LGPL)

This is a bit more liberal than LGPL either, otherwise everybody would have
to linking dynamically to FPC libs, which is technically hard to impossible.
(and not desirable to make that mandatory anyway).

Not for library routines. GPLed library routines are useless. Even GNU
doesn't do that.
