  Following up to the extra enabled warnings for gcc in 1.6, set Visual C++ 
  2005/2008 warning level to 4 to catch more warnings while building on 
  Windows.

For now, specifically disable the following level 4 warnings to keep the 
warning level manageable:
  4100: 'identifier' : unreferenced formal parameter
  4127: conditional expression is constant
  4204: nonstandard extension used : non-constant aggregate initializer
  4701: potentially uninitialized local variable 'name' used
  4706: assignment within conditional expression
Note that apr.h specifically disables the following level 3 warning using 
#pragma:
  4996: 'function': was declared deprecated (level 3)
Which should actually be enabled for Subversion Maintainers.
