Regular expressions aren't working in C++ #36

It seems as though std::regex_search always returns false, and even the simplest regular expressions, such as [0-9]+ or even \d+, throw invalid character exceptions.

Did some more research. This bug seems not to appear when running DJGPP on Ubuntu, only when running it on RHEL. I have no idea why.
