  * On Cygwin, use a Cygwin-style path for /bin/install's destination
  
  cygwin's /bin/install doesn't set file modes correctly if the
  destination path is a C: style path:
  
  $ /bin/install -c -m 644 foo /cygdrive/c/cygwin/home/ian/foo2
  $ /bin/install -c -m 644 foo c:/cygwin/home/ian/foo3
  $ ls -l foo*
  -rw-r--r-- 1 ian None 0 2011-01-06 18:28 foo
  -rw-r--r-- 1 ian None 0 2011-01-06 18:29 foo2
  -rwxrwxrwx 1 ian None 0 2011-01-06 18:29 foo3
  
  This causes problems for bindisttest/checkBinaries.sh which then
  thinks that e.g. the userguide HTML files are binaries.
  
  We therefore use a /cygdrive path if we are on cygwin
