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.
