not sure, if current microsoft compilers are supported, but webkit
currently does not compile with msvc-2012 and msvc-2013:

one issue:
https://bugreports.qt-project.org/browse/QTBUG-31882

as a second issue, msvc-2013 does support c99, so some methods in
WTF/MathExtras.h trigger multiple definitions.

... would be great if both issues could be addressed.
