Using both wchar_t and GCC __attribute__((format(...)))

["Pedro de Medeiros" <pedrovmm+lists@gmail.com>]

Hello,

I am trying to convert some functions in my library from (char *) to
(wchar_t *), and it has been a bit of a nightmare. I want to use GCC error
detection for printf-style functions, but that doesn't seem to work when
functions use wchar_t *. For instance:

void trace(conn_t *, wchar_t *, ...)
        __attribute__ ((format(printf, 2, 3)));

And GCC aborts with:

"error: format string argument not a string type"

Then I tried something like:

void trace(conn_t *, wchar_t *, ...)
        __attribute__ ((format(wprintf, 2, 3)));

But GCC tells me that:

"warning: 'wprintf' is an unrecognized format function type"

Which I assume will disable GCC printf-style error checking.

How do I solve this other than disabling this feature completely?
Any help would be greatly appreciated.

Cheers,
Pedro.
