Subject: [PATCH] w32: Always use standard instead of native format strings

GLib 2.0 include files use __printf__ for the format attribute
5544c1
which resolves to native format strings on w32 hosts.
5544c1
5544c1
QEMU wants standard format strings instead of native format
5544c1
strings, so we simply change any declaration with __printf__
5544c1
to use __gnu_printf__.
5544c1
5544c1
This works because all basic printf functions support both
5544c1
kinds of format strings.

This fixes a compiler warning:

qapi/string-output-visitor.c: In function ‘print_type_int’:

qapi/string-output-visitor.c:34:5: warning: unknown conversion type character ‘l’ in format [-Wformat]
5544c1
qapi/string-output-visitor.c:34:5: warning: too many arguments for format [-Wformat-extra-args]
