 I did not claim my example was valid C++.  And the command line I
 supplied was for invoking a C compiler, not a C++ one.
 
 Apart from the missing `line' directive after the # in the first line,
 it is a valid ISO standard C translaion unit, both according to C89
 and C9x (which got approved last year, I do not know what it is called
 now).
 
 I could probably provide a C++ example, but I do not have the time to
 test right now.  But a C compiler *must* compile every strictly
 conforming C program, which this one becomes if one supplies
 definitions for main and setloglim, possibly in a separate translation
 unit.
