Compiler Warning (level 1) C4600

#pragma 'macro name' : expected a valid non-empty string

You cannot specify an empty string when you push or pop a macro name with either the pop_macro or push_macro.

The following sample generates C4600:

// C4600.cpp
// compile with: /W1
int main()
   #pragma push_macro("")   // C4600 passing an empty string
