does not supply it, the square root function must still
compute square roots.)
These requirements apply to the modified work as a
whole. If identifiable sections of that work are not
derived from the Library, and can be reasonably
considered independent and separate works in
themselves, then this License, and its terms, do not apply
to those sections when you distribute them as separate
works. But when you distribute the same sections as part
of a whole which is a work based on the Library, the
distribution of the whole must be on the terms of this
License, whose permissions for other licensees extend to
the entire whole, and thus to each and every part
regardless of who wrote it.
Thus, it is not the intent of this section to claim rights or
contest your rights to work written entirely by you; rather,
the intent is to exercise the right to control the distribution
of derivative or collective works based on the Library.
In addition, mere aggregation of another work not based on
the Library with the Library (or with a work based on the
Library) on a volume of a storage or distribution medium
does not bring the other work under the scope of this
License.

You may opt to apply the terms of the ordinary GNU
General Public License instead of this License to a
given copy of the Library. To do this, you must alter
all the notices that refer to this License, so that they
refer to the ordinary GNU General Public License,
version 2, instead of to this License. (If a newer
version than version 2 of the ordinary GNU General
Public License has appeared, then you can specify
that version instead if you wish.) Do not make any
other change in these notices.
Once this change is made in a given copy, it is irreversible
for that copy, so the ordinary GNU General Public License
applies to all subsequent copies and derivative works made
from that copy.
This option is useful when you wish to copy part of the
code of the Library into a program that is not a library.
4.
You may copy and distribute the Library (or a portion
or derivative of it, under Section 2) in object code or
executable form under the terms of Sections 1 and 2
above provided that you accompany it with the
complete corresponding machine-readable source
code, which must be distributed under the terms of
Sections 1 and 2 above on a medium customarily used
for software interchange.
If distribution of object code is made by offering access to
copy from a designated place, then offering equivalent
access to copy the source code from the same place
satisfies the requirement to distribute the source code, even
though third parties are not compelled to copy the source
along with the object code.
5.
A program that contains no derivative of any portion
of the Library, but is designed to work with the
Library by being compiled or linked with it, is called
a "work that uses the Library". Such a work, in
isolation, is not a derivative work of the Library, and
therefore falls outside the scope of this License.
However, linking a "work that uses the Library" with the
Library creates an executable that is a derivative of the
Library (because it contains portions of the Library), rather
than a "work that uses the library". The executable is
therefore covered by this License.
Section 6 states terms for distribution of such executables.
When a "work that uses the Library" uses material from a
header file that is part of the Library, the object code for the
work may be a derivative work of the Library even though
the source code is not.
Whether this is true is especially significant if the work can
be linked without the Library, or if the work is itself a
library. The threshold for this to be true is not precisely
defined by law.
If such an object file uses only numerical parameters, data
structure layouts and accessors, and small macros and
small inline functions (ten lines or less in length), then the
use of the object file is unrestricted, regardless of whether
it is legally a derivative work. (Executables containing this
object code plus portions of the Library will still fall under
Section 6.)
Otherwise, if the work is a derivative of the Library, you
may distribute the object code for the work under the terms
of Section 6.
Any executables containing that work also fall under
Section 6, whether or not they are linked directly with the
Library itself.
6.
As an exception to the Sections above, you may also
combine or link a "work that uses the Library" with
the Library to produce a work containing portions of
the Library, and distribute that work under terms of
your choice, provided that the terms permit
modification of the work for the customer's own use
and reverse engineering for debugging such
modifications.
You must give prominent notice with each copy of the
work that the Library is used in it and that the Library and
its use are covered by this License. You must supply a copy
of this License. If the work during execution displays
copyright notices, you must include the copyright notice
for the Library among them, as well as a reference
