[Debian-med-packaging] Bug#748548: Conflicting declarations of jpeg_memory_mgr may lead to invalid function calls

[Michael Tautschnig]

Package: insighttoolkit
Version: 3.20.1+git20120521-5
Usertags: goto-cc

During a rebuild of all packages in a clean sid chroot (and cowbuilder+pbuilder)
the build failed with the following error. Please note that we use our research
compiler tool-chain (using tools from the cbmc package), which permits extended
reporting on type inconsistencies at link time.

Please see #748403, reported against dcmtk, for an analysis of the cause of the
problem. Hooray for embedded code copies.
