Subject: [PATCH] amcl: fix compilation with gcc v7
When building amcl with recent enough gcc v7 compilation fails with
the error
src/amcl/map/map_cspace.cpp: In function 'void enqueue(map_t*, unsigned int, unsigned int, unsigned int, unsigned int, std::priority_queue<CellData>&, CachedDistanceMap*, unsigned char*)':
src/amcl/map/map_cspace.cpp:98:34: error: call of overloaded 'abs(unsigned int)' is ambiguous
unsigned int di = abs(i - src_i);
Use `int abs(int)` flavour of the abs() function.
Upstream-Status: Backported [included in kinetic; will not be backported to indigo releases]
