If using tchar.h forces you to link in msvcrt, it should be moved to
include/msvcrt. Thing is that MinGW supports tchar.h it seems, so we
can do one of two things:
  1. Add conditionals in tchar.h as you suggested to do things differently
     depending on whether or not we link in msvcrt
  2. Move the current tchar.h to include/msvcrt, and create a new one
     to support the MinGW/glibc case.

Alexandre?
