* ext/bigdecimal/bigdecimal.c (isfinite): isfinite does not always
exist. fixed build error on Windows itroduced at r55123. I found that more complex definition of isfinite in numeric.c. But it's unused because it inplicitly checks not defined _WIN32. I don't know why the code do that. IMO, the definition of isfinite should be put at missing.h. git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@55129 b2dd03c8-39d4-4d8f-98ff-823fe69b080e
