dnl Note OSTYPE: On Cygwin we need to use 'cygpath' to convert /cygdrive/c/foo to c:/foo
dnl		 but we must not do that if we aren't building using Cygwin (notably msys), 
dnl		 because cygpath doesn't exist.  It seems that 'bash' sets OSTYPE to 'cygwin' 
dnl		 or 'msys' respectively, but cygwin's 'sh' does not.  So we hackily assume
dnl		 that if the shell hasn't set it to 'msys' then we must be in Cygwin.  Sigh.
dnl
dnl		 The Right Thing is probably to test $BuildPlatform instead, but we are sloppy 
dnl		 about setting that correctly at the moment, so we just work around for now.
dnl
dnl		 The quotes round "$(OSTYPE)" are essential, for the Cygwin-sh case where OSTYPE
dnl		 is not set.
