[issue24872] Add /NODEFAULTLIB:MSVCRT to _msvccompiler

[Christoph Gohlke]

Christoph Gohlke added the comment:

The matplotlib extensions compiled with Python 3.5.0rc1 (/MT) are larger than those compiled with 3.5.0b4 (/MD). The C++ runtime is statically linked. This seems undesirable for the same reasons the UCRT is not linked statically.

In "Introducing the Universal CRT" [1] James McNellis "strongly recommend against static linking of the Visual C++ libraries, for both performance and serviceability reasons". In "Visual Studio 2015 RTM Now Available" [2] the same author commented that one "may deploy the Universal CRT app-locally". Do these comments not apply to CPython?
