 The functions feclearexcept and fetestexcept, used in
 func_eval_expr_int_format, are not available under uclibc environments.
 For that platform, check if the number is finite and within bounds of a
 32-bit signed integer before attempting the cast instead.

 I made the patch against release 2.6.3 but applies cleanly against a git
 clone performed on August 22nd, 2015.
