:   '''file executable''' ''name''

Returns '''1''' if file ''name'' is executable by the current user, '''0''' otherwise.

[MHo] 2010-11-11: Seems not work as expected on MS Windows. file executable gives 0 for a program which is definitely callable. The program resides on a mapped network drive (maybe this is important).

[AMG]: It works for me, on Windows XP.  [[file executable]] returns 1 for *.exe files and directories, probably others too.  It returns 0 for *.dll and *.tcl, I noticed.  I'm using a very recent Tcl 8.6 CVS I built myself using [MinGW].

[MW]: The problem with Windows and network drive was discussed at http://sourceforge.net/p/tcl/bugs/3985/
