use <regex> <locale> make pakckage fail to be loaded on 64bit Windows R EXPERIMENTAL

[qinwf]

I have made a small package to replicate this issue. https://github.com/qinwf/testlocale .

For 32bit R it works fine. This function will remove punctuation in Chinese locale using c++11 regex with wstring.

library(testlocale)
rcpp_hello(c("test","你好","。","；","】","]"))
#[1] "test" "你好"

For 64bit R.

There is another package, which has some similar functions, will fail to be installed on 64bit R and it will work on 32bit R.
