File xclass-0.9.2-gcc6.patch of Package xclass

bts: #1041255
Author: i@marguerite
Summary: fix narrowing conversion from int to char inside {}

Author: Adam Majer <amajer@suse.de>
Summary: use signed calculations when calling abs(x)

Use signed variables when doing a "distance" calculation.
Callng abs(x) on unsinged is pointless, since all values
are always >0. But since the code actually assumes signed
arithmetic, but uses unsigned - fix the code.
