Re: not a bug but some strange behaviour

[jean-luc malet]

found!
I was using SHELL = /bin/sh
I shall have used SHELL = sh
and in fact make behave differently if the path is inside the SHELL variable....
info make in section choosing the shell....
however I find this strange and confusing that make behave differently
on dos/windows than on cygwin/unix....
