[osol-discuss] warning with variadic macro

Hey,

i am contributing to a project (the Enlightenment windows manager) and we use 
variadic macros. More precisely, this one:

#  define EINA_ARG_NONNULL(idx, ...) __attribute__ ((nonnull(idx, ## 
__VA_ARGS__)))

and we use it like that (for example):

EAPI void eina_rectangle_pool_free(Eina_Rectangle_Pool *pool) 
EINA_ARG_NONNULL(1);

On Linux, no problem, but on opensolaris, a guy reported the warning using 
SunStudio12 :

"warning: argument mismatch"

I'm not very familiar with variadic macro, and even if google found some pages 
about that (like 
http://mail.opensolaris.org/pipermail/opensolaris-code/2008-September/006029.html
 ), i didn't find the solution.

So, is there a flag to pass to the SunStudio12 preprocessor and/or modifying 
the above macro ?

thank you

Vincent Torri
