[Bug c/40065] New: spurious format string warnings

["bje at gcc dot gnu dot org" <gcc-bugzilla at gcc dot gnu dot org>]

When GCC cannot recognise a format specifier, it produces spurious warnings. 
For example:

gcc/coverage.c:364: warning: unknown conversion type character ?E? in format
gcc/coverage.c:364: warning: format ?%qs? expects type ?char *?, but argument 3
has type ?tree?
gcc/coverage.c:364: warning: too many arguments for format

In this case, %qE was not recognised by the compiler.  It should skip the
corresponding argument and continue to check the remaining format specifiers
and arguments.  At present, it tests the second format specifier against the
first argument, and so on.
