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.

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.
7 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.
