C++ warnings on JaroWinkler.create native

[scottbarrow]

jarow = FuzzyStringMatch::JaroWinkler.create( :native )
cc1plus: warning: command line option '-Wdeclaration-after-statement' is valid for C/ObjC but not for C++
cc1plus: warning: command line option '-Wimplicit-function-declaration' is valid for C/ObjC but not for C++
=> #<FuzzyStringMatch::JaroWinklerInline:0x005611f1998618>

It seems to originate from https://github.com/kiyoka/fuzzy-string-match/blob/master/lib/fuzzystringmatch/inline/jarowinkler.rb#L44

gcc version 4.9.2 (Debian 4.9.2-10)
