Tcl Source Code

System: WinXP, Tcl/Tk 8.5 CVS (current), Mingw gcc 3.4.2

i get these problems when creating absolute directories:

% file mkdir .                          <-- no error here
% file mkdir c:/
can't create directory "c:/": permission denied
% file mkdir c:/windows
can't create directory "c:/": permission denied
% file mkdir c:/w
can't create directory "c:/": permission denied
% file mkdir /home
can't create directory "/": permission denied

In function TclFileMakeDirsCmd (tclFCmd.c:222) it
checks if the destination target exists, and if it is
not a directory, it will attempt to create it. But, if
it does exist and is a directory it will still call
Tcl_FSCreateDirectory.

patch is attached with proposed fix (which seems
reasonable to me).

I havent tested it on other platforms (no idea if it
has any impact on symlinks since i did not look inside
function Tcl_FSCreateDirectory.

Fixed this, and made sure tests pass correctly.  Also added
more comments so code paths are clearer.
