On uClibc, finite, isinf and isnan are not directly implemented as functions. Instead math.h #define's these to __finite, __isinf and __isnan, which are real functions. This confuses the Ruby configure script which use AC_REPLACE_FUNCS to detect these, as it really checks for a function without including math.h. Because of the naming difference the checks fail, therefore the symbols HAVE_FINITE, HAVE_ISINF and HAVE_ISNAN are not defined. Ruby code relies on those symbols in order to define its own version of the finite, isinf and isnan functions. Since the symbols haven't been defined, those definitions cause conflicts with the already-existing functions.
