Subject: [PATCH] src/suncalc.cpp: fix build with gcc 6.x

​

src/suncalc.cpp currently includes <math.h>, but this causes a build

failure with gcc 6.x, and <cmath> should be used instead. The build

failure is:

​

/home/test/autobuild/run/instance-0/output/host/usr/arc-buildroot-linux-uclibc/include/c++/6.1.1/cmath:101:37: error: '__is_integer' was not declared in this scope

     typename __gnu_cxx::__enable_if<__is_integer<_Tp>::__value,

                                     ^~~~~~~~~~~~
