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.
