Bug#352133: gs-gpl: Font rendering on 64bit platforms
Package: gs-gpl
Version: 8.15-4.1
Severity: important
On amd64 certain ps and pdf files (for instance ones created by OpenOffice)
are incorrectly rendered in very small text size, both on screen and printout.
The newest (non-GPL) upstream version fixes this, see also
http://bugs.ghostscript.com/show_bug.cgi?id=688047.
The bug is caused by the implicit assumption that 'long' is 32bit in three headers.
Attached below is a patch to fix this based on my understanding of the issue.
