I brought this up back in ruby-talk:104505.  It
appears to be a bug in cl.exe.  It would be easy
enough to patch this by wrapping all paths on Windows
with GetShortPathName().  This could be done with the
Win32API package:

require "Win32API"

GetShortPathName =
Win32API.new("kernel32","GetShortPathName","PPL","L")

path = "C:\\program files\\mozilla firefox"
buff = 0.chr * 260
GetShortPathName.call(path, buf, buf.length)
short_path = buf.split(0.chr).first

p short_path # "C:\\PROGRA~1\\MOZILL~1"

The only potential gotcha, iirc, is that short paths
can be disabled as a filesystem speedup tweak, so it
wouldn't help people who had done that.  I think it's
better than nothing, however.

Regards,

Dan
