> Make gtest always use simple internal regex engine.
> 
> In order to allow regex matches in gtest to be shared between Windows and other
> systems, we tell gtest to always use it's internal engine.
> 
> The syntax supported by the internal engine initially looks like a subset of
> POSIX regexs. However character class shortcuts are not valid POSIX.
> 
> Even more confusingly the system POSIX regex function often defines extra
> features not actually part of the standard allowing regex that work on Linux
> fail on Mac OS X.
> 
> A search through the code base did not reveal any locations where features not
> supported by the internal regex engine where used.
