Patch
On VxWorks, ioctl()'s third argument is of type int, so this added
macro wraps over ioctl to cast the third argument to an integer.
This *cannot* be in config/os/vxworks/os_defines.h as otherwise
the function prototype will trigger the macro and it will be ugly.
Alternate solution is to #ifdef at the call site.
Attached patch is against trunk. Without it the compile fails because VxWorks
ioctl() requires third argument to be of type int, and C++ doesn't allow
implicit conversion from pointer to integer.
