Under WIndows XP I cannot copy these files
sys\src\9\boot\aux.c
sys\src\cmd\con\con.c =)
and these directories
sys\src\cmd\con\
sys\src\cmd\aux\
from Plan 9 source tree, because Windows don't allow anyone create
directories or files with names "aux", "con".
*LOL*

lol indeed; thanks to backward compatibility. Back in the heyday of DOS, you
could
copy CON FILE.txt
(typety typety typety)
^Z
and you got a nice file :D
or, perhaps,
copy FILE.txt LPT1
and have it printed
in any case, the limitation is not in filesystem, neither in handling of
directory access; there's a `hack' involving a somewhat twisted pathname to
create the directory; see the discussion at
http://kerneltrap.org/node/5772

You can create these objects using the CreateFile() API but you
must add the Posix semantics flag. This will also allow you to create
Makefile and makefile in the same directory.
The problem is that you will not be able to access these files
from Windows/MSDOS.
Sadly this means that almost noone uses Posix semantics.

It used to be possible to crash Windows remotely via the web, simply
by using a file URL containing two or more of these reserved words.
Possibly fixed by now.

I used to troll SAMBA file servers with such dirs when I was younger.
They had funny names and nobody knew how to remove them.

you can still access these "special" file names by prefixing your path
with \\?\
example:
C:\>echo Test > "\\?\C:\AUX"
C:\>dir "\\?\C:\AUX"
Volume in drive \\?\C: is SYS
Volume Serial Number is D48F-6BD6
Directory of \\?\C:
07.01.2011 00:19 7 AUX
1 File(s) 7 bytes
0 Dir(s) 0 bytes free
C:\>type "\\?\C:\AUX"
Test
C:\>

patch for drawterm should be trivial...
