[3dprinter-general] Bug#1020779: Bug#1020779: slic3r-prusa: FTBFS on 32-bit arches

[Gregor Riepl]

Do you have a bit more context for this?

 From the log, I can't see what the actual issue is.
Is it an autoconf check that fails or an actual compilation issue?

If it's a check, which one?

If it's actually in the source, the error doesn't make any sense. 
Compilation is done without -Werror, and the deprecation message is only 
a warning.
