* Update LICENSE's md5sum, the new version added a "of" in the file, the
license is the same.
* Remove ghostscript-9.02-parallel-make.patch, it has 932 lines and
modified 24 files, which is hard to maintain, and it can't be applied
since the code has changed, and if we meet parallel issues again, we
need fix it in other ways.
* Fix a build error of -Werror=return-type.
