It isn't lower standards, it's what the compiler defaults to.  If the 
compiler can't be made to enforce strict compliance, that's a bug.  By 
the way I often hit this problem compiling poor opensource code written 
with gcc when compiling with Sun's cc which has a much stricter default 
mode.

Where the standard requires a diagnostic, a warning is a diagnostic.  If 
you want an error, use whatever option the compiler has to turn warnings 
into errors.
