No, lots of pedwarns are for usages that are (a) dubious enough we want to 
diagnose them by default, and (b) required to be diagnosed by ISO C so 
must become errors with -pedantic-errors.  (You could argue about whether 
we should have -fpermissive for C like for C++ and make some of those into 
errors by default.)
