So, an implementation's behavior does not define correctness,
the language standard does.
The above ((even without the 'stdafx', with _tmain() changed to 'main(),
and _TCHAR changed to 'char'), is *not* standard compliant code.

Same remarks as above.

<OT>
It's in the menus. I don't know where in 7.1, but in 6.0
it's in the 'Project Settings' dialog, "C/C++" tab, category
"Precompiled headers". There are choices to not use, use
'automatic', or use 'manually'.
