-dnl Note OSTYPE: On Cygwin we need to use 'cygpath' to convert
-dnl              /cygdrive/c/foo to c:/foo but we must not do that if we
-dnl              aren't building using Cygwin (notably msys), because
-dnl              cygpath doesn't exist.  It seems that 'bash' sets
-dnl              OSTYPE to 'cygwin' or 'msys' respectively, but cygwin's
-dnl              'sh' does not.  So we hackily assume that if the shell
-dnl              hasn't set it to 'msys' then we must be in Cygwin.
-dnl              Sigh.
