Where is sys/ioctl.h supposed to come from?

[Peter Dufault]

I just noticed that this C code:

#include <sys/ioctl.h>
void foo(void){}

fails with:
[dufault at pico tmp]$ powerpc-rtems4.7.1-gcc -c foo.c
foo.c:1:23: error: sys/ioctl.h: No such file or directory
[dufault at pico tmp]$

on ALL the rtems development environments I've got available going back to the above 4.7.1.

There are sys/ioctl.h files in the BSP subdirectories but not in the usual include/sys directory.  For example, for the 4.11 I've got:

[dufault at finny12 tmp]$ find /opt/rtems-4.11/ -name ioctl.h -print
/opt/rtems-4.11/powerpc-rtems4.11/beatnik/lib/include/sys/ioctl.h
/opt/rtems-4.11/powerpc-rtems4.11/phycore_mpc5554/lib/include/sys/ioctl.h
[dufault at finny12 tmp]$ 

What step have I been missing all these years?  Here's a verbose trace, is it something to do with my nonexistent "sys-include" directory?

[dufault at finny12 tmp]$ cat foo.c
#include <sys/ioctl.h>
void foo(void) {}
[dufault at finny12 tmp]$ powerpc-rtems4.11-gcc -v -c foo.c
Using built-in specs.
