Fixes to build under High Sierra

[tonigi]

Had to do the following (I'm using the command line developer tools)...

I'd advise you to keep the -Wall, or move it before the -isysroot. If you're using 10.12 or 10.13, you may want to update it to simply /Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX10.12.sdk or /Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX10.13.sdk or wherever your SDK is. Or add a test in the Makefile.

Updated to fix the SDK and std::string issues.
