It would be nice if MSVC will create something like clang-cl [1] to handle --options like others do, for easier compiling of pure Makefile opensource projects.
Why use MSVC at all when Clang has a perfectly good gcc-style driver? There's also this http://git.savannah.gnu.org/cgit/automake.git/tree/lib/compi... wrapper script which is useful once in a while for invoking MSVC from inside Cygwin or MSYS (though MSYS2 broke this, last I checked).
We (radare2 project) already being built by gcc, clang and tcc. Every time new compiler support added it reveal some new errors. This is why we have interest in trying MSVC too.
Thank you for the script!
