fcntl-h, stdio, sys_ioctl: fix declarations We cannot use a function-like macro to provide a link-time warning of a variadic function during GNULIB_POSIXCHECK; at least, not without assuming C99 variadic macros. We can, however, use an object-like macro (as was already done for printf). On the other hand, this patch is only a stop-gap measure to fix an obvious bug; a more complete patch that switches from a link-time warning (specific to GNU ld, gcc, and ELF image) to a compile-time attribute is in the works. * lib/stdio.in.h (dprintf): Use of link warning on a variadic function must not take arguments. * lib/sys_ioctl.in.h (ioctl): Likewise. * lib/fcntl.in.h (openat): Likewise. Declare extern. (open): Add a link warning. Signed-off-by: Eric Blake <ebb9@byu.net>
