[sane-devel] sane-backends effectively GPL'd in disguise?

I have been upgrading "Image Scan! for Linux" to use SANE internals from
sane-backends-1.0.12. Ever since the FSF slapped us on the wrist for an
unintentional violation of the GPL, we have a little allergic to license
issues so I combed through the include/, lib/ and sanei/ directories for
The following files in include/ and sanei/ are GPL'd *without* the SANE
Even though I have read the GPL twenty+ times over, I am still not sure
whether this means that files including any of these would effectively
void their SANE exception (assuming they have one). After all the SANE
exception explicitly states:
This exception does not, however, invalidate any other reasons why
the executable file might be covered by the GNU General Public
Ergo, files like sanei/sanei_scsi.c and sanei/sanei_usb.c, which include
their counterpart header files, might in effect be released under the
GPL and the GPL only without any SANE exception. The same logic applies
to backends including files from the above list.
The TODO notes that the getopt*.c and md5.c files have been checked for
(and replaced by LGPL'd versions) precisely the reasons cited above.
Could anyone shed any light on this?
