src/hhalign/util-C.h defines float log2(float) and float log10(float) inline functions which conflict with those in <math.h>. (The proper name for these signatures in the C standard library are log2f and log10f.) Removing those two functions fixes the build (std::log2 and std::log10 are used in their place).

Thanks Yaakov for not just showing me how to fix it, but also for the explanation of what the code does...
