Compiler Error C2850

'construct' : only allowed at file scope; may not be in a nested construct

Constructs, such as some pragmas, can only appear at global scope.

The following sample generates C2850:

// C2850.cpp
// compile with: /c /Yc
// try the following line instead
// #pragma hdrstop
namespace X {
   #pragma hdrstop   // C2850
};
