-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.
