Fix build with -directwrite

Browse Source 
There were several issues caught by GCC:
* deleting object of polymorphic class type which has non-virtual
  destructor might cause undefined behaviour
* comparison between signed and unsigned integer expressions
* 'GetUserDefaultLocaleName' was not declared in this scope
  (depends on WINVER >= 0x0600)
