Conveying Modified Versions.

If you modify a copy of the Library, and, in your modifications, a facility refers to a function

or data to be supplied by an Application that uses the facility (other than as an argument

passed when the facility is invoked), then you may convey a copy of the modified version:

under this License, provided that you make a good faith effort to ensure that, in the event

an Application does not supply the function or data, the facility still operates, and performs

whatever part of its purpose remains meaningful, or

under the GNU GPL, with none of the additional permissions of this License applicable to

that copy.

Object Code Incorporating Material from Library Header Files.

The object code form of an Application may incorporate material from a header file that is

part of the Library. You may convey such object code under terms of your choice,

provided that, if the incorporated material is not limited to numerical parameters, data

structure layouts and accessors, or small macros, inline functions and templates (ten or

fewer lines in length), you do both of the following:

Give prominent notice with each copy of the object code that the Library is used in it and

that the Library and its use are covered by this License.

Accompany the object code with a copy of the GNU GPL and this license document.

5. Combined Works.

You may convey a Combined Work under terms of your choice that, taken together,

effectively do not restrict modification of the portions of the Library contained in the

Combined Work and reverse engineering for debugging such modifications, if you also do

each of the following:

Give prominent notice with each copy of the Combined Work that the Library is used in it

and that the Library and its use are covered by this License.

Accompany the Combined Work with a copy of the GNU GPL and this license document.

For a Combined Work that displays copyright notices during execution, include the

user to the copies of the GNU GPL and this license document.

Do one of the following:

0) Convey the Minimal Corresponding Source under the terms of this License, and the

Corresponding Application Code in a form suitable for, and under terms that permit, the

user to recombine or relink the Application with a modified version of the Linked Version

to produce a modified Combined Work, in the manner specified by section 6 of the GNU

GPL for conveying Corresponding Source.

Use a suitable shared library mechanism for linking with the Library. A suitable

mechanism is one that (a) uses at run time a copy of the Library already present on the

user's computer system, and (b) will operate properly with a modified version of the

Library that is interface-compatible with the Linked Version.

Provide Installation Information, but only if you would otherwise be required to provide

such information under section 6 of the GNU GPL, and only to the extent that such

information is necessary to install and execute a modified version of the Combined Work

produced by recombining or relinking the Application with a modified version of the Linked

Version. (If you use option 4d0, the Installation Information must accompany the Minimal

Corresponding Source and Corresponding Application Code. If you use option 4d1, you

must provide the Installation Information in the manner specified by section 6 of the GNU

GPL for conveying Corresponding Source.)
