In spite having no time for unimportant stuff like that I am still to curious if the updated toolchain on hppa automagically fixes bug #107437 so I logged into sarti.debian.org and tried to build gs there. libgimpprint-dev is not installed so the build will not be complete but anyway it should suffice to test basic functionality.
Okay, now it does not even build anymore. It is stuck in a tool that tries to detect the characteristics of the build system. 0% cpu usage in a memset loop!? Never mind...
