[Debian-med-packaging] Bug#749783: gdcm: Conflicting declarations of jpeg_memory_mgr may lead to invalid function calls

[Michael Tautschnig]

Package: gdcm
Version: 2.4.2-1
Usertags: goto-cc

During a rebuild of all Debian packages in a clean sid chroot (using cowbuilder
and 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.
