What I'm missing here is the information how the environment looks
like in terms of the TMP/TEMP variables *before* calling envprint.
Without this the testcase is rather incomplete.

For testing I did

  tcsh$ setenv TEMP /tmp
  tcsh$ setenv TMP /tmp
  tcsh$ ./envprint | grep -i tmp
  'TEMP=C:\cygwin\tmp'
  'TMP=C:\cygwin\tmp'

same result on 32 bit W7 and 64 bit W2K8R2.
