Re: not a bug but some strange behaviour

[jean-luc malet]

almost....
it seems that it fixe the shell script but if I call some dos tool
inside, then the env is striped again....
some other points :

if I wrap the cmd into a shell all is working :
sh$ tail -F /tmp/cmd.file | cmd > /tmp/log.file &
sh$ echo cd the\\path\\to\\the\\make.bat\\ >> /tmp/cmd.file
sh$ echo make.bat test >> /tmp/cmd.file
sh$ cat /tmp/cmd.file; #all is ok

so it seems really related to the fact that make behave differently if
launched in a cmd or if somewhere else before a cygwin session as been
created....
