CI also tests FreeBSD 11, MSVC 2015 & 2017 and MacOSX, and all are successful 
on the whole test suite.
I see that geodesic.c has seen non trivial changes between 6.2.1 and 6.3.0, 
one of them being that we rely on C99 for PROJ builds. Is your setup (compiler 
+ libc) of netBSD 8 C99 compliant?
You might try building with -DHAVE_C99_MATH=0 to check that.
