I'm posting my response (which should not be taken as an official
X3J11 position) because it may be of general interest:

X3J11 (the ANSI C committee) didn't want to try to dictate any
details of how C compilers are invoked, and they didn't want to
specify any form of multiple "levels" of the standard.  Vendors
will in many cases provide a variety of options, but only the
standard-conforming mode of operation will be covered by the
ANSI/ISO C standard specification.  You can try to convince your
compiler vendor that the option you suggest is a good idea..
