| How about something like

| warning: format '%s' expects a char *, but argument 2 has type float *
| 
| (i.e., giving the particular format with bad argument type)?

Absolutely.  Apart from not using the GNU coding style, the
pretty-printer in gcc/c-pretty-printer.[hc] is ready for used in the
C front-end.  If you plan to use it before I complete the new C++
pretty-printer, please don't lose the style :-)

[Note: The current pretty-printer will print "char*" (C++ style)
       as opposed to "char *" (GNU style). ]
