Better to make it -fmicrosoft_version=15.0

This is because of history; there have been several separate MS 
C/C++ compilers, and at least one reset of the marketing version 
number, at "Visual C++ 1.0" when an existing compiler that had
several versions was bundled with a new IDE. The version number 
sequence for the actual compiler has progressed smoothly for 
about 20 years now, and is probably worth sticking with. 

Incidentally, there's an undocumented option, /Bv, on the MS 
compiler that produces a full and proper account of the version 
numbers of the compiler and its components. This is handy when 
trying to sort out details of differences between versions
