POSIX uses 'restrict' in *wprintf() (see [v]fwprintf(3p)). Let's use it here too. Signed-off-by: Alejandro Colomar <alx.manpages@gmail.com> --- Hi Michael, I found this last one, which I didn't find through the glibc sources because they have a bit of a mess with *printf() functions. I checked that POSIX requires 'restrict'. At this point, I still have a few patches about prototypes (not restrict), but I'll buffer them for now.
