Fix cygwin build - moves to C++11 regex
* Fixing cygwin builds by not mingling them with the rest of win32 * Include sys/select.h in CYGWIN to define fd_set * Add fd_set definition ahead of microhttpd.h inclusion * suppress ignore_sigpipe for cygwin * Add missing includes * Remove runguard (not used) * Remove runguard (unused) * Import definition of NI_MAXHOST in cygwin * Force in definitions needed by cygwin * Define u_char for cygwin * Remove regex_replace method that was never used. * Removed regex_replace method that is never used * Remove regex_replace method that is never used * Move to C++11 regex * Use C++11 regex * Prevent object from not being initalized * Use std::regex rather than std::basic_regex * Use std::regex instead of std::basic_regex * Fix typos * Reorder parameters to avoid warnings * Remove requirements for libregex
