Fix compilation in Visual C++ 2013.
I had to fix the following things to make Ceres compile in 2013:
* Not link to 'm' (GNU math library).
* Excplicitly convert an std::ostream to bool.
* Include <algorithm> for std::max.

# As this is a C file #including <math.h> we have to explicitly add the math
# library (libm). Although some compilers (dependent upon options) will accept
# the indirect link to libm via Ceres, at least GCC 4.8 on pure Debian won't.
