Porting CFNetwork to VS complier

First import thing to note is compiler differences on difference platforms - Visual Studio 2008 supports C90 standard. A newer complier was used to develop CFNetwork. Hence the most important differences:

  • All variable definitions must be placed at the beginning of each scope (otherwise it fails with "illegal type as an expression" errors)
  • C90 allows structure initialization only by compile time constants (no pointers or even constants pointers to constant data)
  • inline support - Visual studio uses keyword __inline (double underscore is required)
  • Visual Studio compiler does not allow double class storage specifier such as "static static int var"
