If I employ a BSD-style licence, then you can choose to use a similar
licence yourself, to use a proprietary licence and to not provide your
source, or even to distribute _your_ software, even as a derived work,
under the terms of the GPL.
If, on another hand, I grant you use under the terms of the GPL, then
you are still free to write your software, but if you link your program
with mine (isn't that what the headers are for?), then any distribution
you do must be under the terms of the GPL, and you must (if asked)
produce the source on demand.
AFAIK, this has not been tested in court, and ISTR hearing that there is
court precedent that linking a program with a library does
not (LGPL language notwithstanding) create a "derived work".
It does, however, mean that you must abide by the terms of use and
distribution for the library. The new terms in GPL3 make it EXTREMELY
unlikely that life will go on as before in the GPL world. There will
be no further linked in video drivers in precompiled form, for example.
Wording in GPL3 prohibits this. So either Linux does not adopt GPL3 and
refuses to include any GPL3 code or Linux dies for lack of specialized
driver support. RMS is, predictably, a silly turd.
