Compilation fix for Borland compiler bug with ternary operator.

Don't use ?: operator with references, Borland wrongly deduces the common type
as being an object in this case, so use pointers instead and dereference later.

See #16592.

Compilation fix for Borland overload selection bug.

Avoid the following bogus compiler error:

Error E2015 ..\..\src\common\filename.cpp 2589: Ambiguity between 'wxFileName::Exists(int)
 const at ..\..\src\common\filename.cpp:777' and 'wxFileName::Exists(const wxString &,int)
 at ..\..\src\common\filename.cpp:790' in function wxFileName::SetPermissions(int)

by using an unambiguous overload.

See #16592.

Fix resource compiler include path for Borland.

Explicitly include $(BCCDIR)/include/windows/sdk directory in the resource
compiler options, as it needs it to find windows.h.
