Hello,
may I ask if it is possible to call any function with prepared va_list?
I mean how can I construct call when I have my own constructed va_list, pointer
in form "int (*func)()" to function e.g. "int func(int a, int b, int c)".
Maybe "__builtin_apply" could solve this problem, but I am unable to find any
information about how to build arguments to this function (something similar
that __builtin_apply_args returns but in my own).
Thanks for any ideas?
PS: How can I register to get all e-mails from this maillist? I am not even sure
if this is maillist :)

You want the libffi library, which is provided with gcc but is not
part of the compiler itself.

You really want the gcc-help@gcc.gnu.org mailing list. This list is
about how to write GCC, not how to use it.
