* io.c (ioctl_narg_len): don't use _IOC_SIZE macro on Linux.
On Linux some constants for ioctl(2) doesn't include the size of its return value and 16bit value; for example FIONREAD 0x541B. Moreover the manual, ioctl_list(2), says "Note that the size bits are very unreliable: in lots of cases they are wrong, either because of buggy macros using sizeof(sizeof(struct)), or because of legacy values." So we shouldn't use it. git-svn-id: svn+ssh:// b2dd03c8-39d4-4d8f-98ff-823fe69b080e
