For fullness, the current files which include sys/ioctl.h without 
checking are:

/src/gdb/gdbtk/generic/gdbtk.c
/src/gdb/gdbtk/generic/gdbtk_cmds.c
/src/gdb/gdbtk/generic/gdbtk_hooks.c

Let me know if you want me to send a patch for exclusion of 
<sys/ioctl.h> if it doesn't exist.

You should be able to get the mingw compiler setup on your linux box, 
but if it is an unsupported target I guess it's not a priority.

Dave Murphy forwarded me a patch (thank you very much for that Dave!) 
and with that I was successful in building a working 6.6 
arm-elf-insight.exe under mingw.

Eric, target=avr also built correctly for 6.6 (as does cvs with a few 
changes to Dave's patch)

Hopefully Dave will be able to make his patches available soon (If you 
need any help with those Dave, please shout) and cvs will be buildable 
on mingw out-of-the-box.

Thanks for everyone's help.

Best Regards,

Brian Sidebotham.
