[Debian-med-packaging] Bug#860652: snap-aligner: FTBFS on i386: SNAPLib/SortedDataWriter.cpp:338:70: error: no matching function for call to 'max(long unsigned int, _int64)'

[Andreas Tille]

Hi,

some hours ago the Debian Med team was flooded with lots of bugs
regarding build on i386 - I guess this is not the only team.  I need to
admit I'm a bit astonished about this kind of bugs that are showing up
right now ... may be autobuilding on i386 started right now?

Anyway.  I try to tackle the first one which leaves me clueless.  Any
idea why max() and min() are unknown now but were not before?

Kind regards

       Andreas.
