Using uint32_t for ioctl_command_t does not work well on 64-bit targets.

Why do you need a ioctl_command_t at all?  It's not in FreeBSD either.

Its used by the legacy network stack in RTEMS (e.g. various device 
drivers). I don't know who introduced this type and why. glibc has also 
simply "unsigned long".

Ok.  At this point I would have replied "please apply", but you
already did that.  It's write *after* approval ;)

Sorry for the rush.

So, you are not particularly fond of having OS port maintainers in 
Newlib similar to GCC?

It's more about timing.  From write-after-approval to writing w/o
approval in less than an hour?  Talking about rushing things...
