Alexander Richardson 7c36a9e24a Fix -Werror,-Wmacro-redefined in limits.h
Those macros are also defined by the compiler-provided float.h which
will be included later on (at least in the FreeBSD buildworld case) and
triggers these -Werror warnings. Including <float.h> first and only
defining the macros when DBL_DIG/FLT_DIG is missing fixes this problem.
