merge revision(s) 36522: [Backport #7016]
* include/ruby/win32.h (rb_w32_pow): add new function. We use powl() instead of broken pow() for x64-mingw32. This workaround fixes test failures related to floating point numeric. [ruby-core:46686] [Bug #6784] git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/branches/ruby_1_9_3@37024 b2dd03c8-39d4-4d8f-98ff-823fe69b080e
