There is no need to compile our DLLs as shared libraries since we are
managing symbols exports and imports through spec files.
On my system, this reduces the configure-time by a factor of two.
- Add missing parameter to a DPRINT.
- Print pointers using %p instead of %x.
- Move all executable code behind a functions initial DPRINT.
- Do not use non-trivial initializers.
- Check for NULL instead of using !.
- Add missing parentheses.
