GCC will warn about invalid format specifiers in format strings with printf and
similar functions. However, the list of format specifiers that GCC warns about
is the specific list given in the ANSI/ISO C standard. However, many runtime
libraries (including the runtime library used on the MingW target, which is the
standard windows C runtime from Microsoft) support extra format specifiers (for
example, the Microsoft runtime supports %wZ for printing out a special kind of
string used by the windows kernel). Basicly, this is a request for a feature
(perhaps in the SPEC file) to enable specific implementations to add/modify the
list of which format specifiers GCC will warn about.
I do know that you can turn the warning off with -Wno-format but that defeats
the purpose of format argument validation.
Directly related to this would be a way to specify that a particular function
(and argument to that function) should be interpereted as a format specifier
string and checked as such.

2622 last time (i.e. today) I looked at the number vs. 3670 new;-(

No, be bold and close stuff. So much useless open stuff that nobody cares
anymore about the ~2000 unconfirmed bugs.

------- Comment #2 from ktietz at gcc dot gnu dot org 2009-09-10 09:33 -------
This feature was added to 4.4.0 and there are now format specifiers for ms and
gnu printf/scanf styles.
As this feature won't be backported to 3.4.0, this bug should be closed.
Danny any objections about this?
