 libfprint
 =========
 libfprint is part of the fprint project:
 https://fprint.freedesktop.org/
 libfprint was originally developed as part of an academic project at the
 University of Manchester with the aim of hiding differences between different
 consumer fingerprint scanners and providing a single uniform API to application
 developers. The ultimate goal of the fprint project is to make fingerprint
 scanners widely and easily usable under common Linux environments.
 The academic university project runs off a codebase maintained separately
 from this one, although I try to keep them as similar as possible (I'm not
 hiding anything in the academic branch, it's just the open source release
 contains some commits excluded from the academic project).
 THE UNIVERSITY OF MANCHESTER DOES NOT ENDORSE THIS THIS SOFTWARE RELEASE AND
 IS IN NO WAY RESPONSIBLE FOR THE CODE CONTAINED WITHIN, OR ANY DAMAGES CAUSED
 BY USING OR DISTRIBUTING THE SOFTWARE. Development does not happen on
 university computers and the project is not hosted at the university either.
 For more information on libfprint, supported devices, API documentation, etc.,
 see the homepage:
 https://fprint.freedesktop.org/
 libfprint is licensed under the GNU LGPL version 2.1. See the COPYING file
 for the license text.
 Section 6 of the license states that for compiled works that use this
 library, such works must include libfprint copyright notices alongside the
 copyright notices for the other parts of the work. We have attempted to
 make this process slightly easier for you by grouping these all in one place:
 the AUTHORS file.
 libfprint includes code from NIST's NBIS software distribution:
 http://fingerprint.nist.gov/NBIS/index.html
 We include bozorth3 from the US export controlled distribution. We have
 determined that it is fine to ship bozorth3 in an open source project,
 see https://fprint.freedesktop.org/us-export-control.html

 Subject: [PATCH] nbis: fix build on musl
 Drop re-definition of stderr. There's no need for this anywhere
 (including glibc). This breaks in particular on musl because
 stderr (and stdin) are both const, and macros unlike in glibc.
 Bug: https://bugs.gentoo.org/853811
