That's just your opinion.

Not /just/ his opinion.

The C Standard explicitly permits implementations
to emit as many diagnostics as they deem fit, over and above what are
required by it.

Sure - but I suspect most people here would agree that any compiler
that emits diagnostics with valid code is screwed up.

Otherwise where do we draw the line ?

warning: "int" - you should use either short or long (or possibly long
long) as the size of an int is platform dependent and your code will
be hosed when you port to a 128-bit platform..

warning: 's' - you do realise this has different sizes in C and C++

warning: 'C' - this is a Fortran comment indicator, your code will
break if you crosscompile with Fortran

warning: "scunthorpe" - this identifier is obscene, reporting you to
the VGTF and Interpol

warning: "tee" - ambiguous identifier: darjeeling or lapsang ?

fatal: "windows" - this word is copyright, deleting your source code
