I don't know the Guile license, but this is the exeption that GNU Classpath
project uses to allow linking with anything not GPLed. (All Classpath code
is copyrighted by the FSF.) I expect that the Guile license is almost the
same. Note that this exception does not apply if any other GPLed code is
added (then it reverts to plain GPL).

	GNU Classpath is free software; you can redistribute it and/or modify
    it under the terms of the GNU General Public License as published by
    the Free Software Foundation; either version 2, or (at your option)
    any later version.
	[... No Warranty, ..., You should have received a copy of the GPL ...]
    As a special exception, if you link this library with other files to
    produce an executable, this library does not by itself cause the
    resulting executable to be covered by the GNU General Public License.
    This exception does not however invalidate any other reasons why the
    executable file might be covered by the GNU General Public License.
