              Function 'InitPsuedoGlobals' may return constant 'NULL' at line 183, called at line 153.
              Null pointer introduced at line 183 in function 'InitPsuedoGlobals'.

    Provide a fallback mkstemp so we don't need to maintain 2 API versions
    
    Unifies the file handling API's to always return an open fd or FILE *,
    instead of delaying the open when mkstemp was not available.
