There is a special clause in the GPL (and presumably in the LGPL) about
system libraries.  This was necessary for the original writing of free
software, before it made a complete OS.

Also, there is no requirement that you distribute the source with the
binaries, so long as you make available the source on request at the only
cost of providing it.

If A equals success, then the formula is A = X + Y + Z.  X is work.  Y
is play.  Z is keep your mouth shut.
