Not if they were using glibc, certainly; dev_t is defined in
<bits/types.h> (included by <unistd.h>, of course), which is
unconditionally installed and not dependent on architecture, nor on any
of the __USE flags. So *everyone* should have this.

What libc is this system using? Maybe it's using uClibc or something...
