Thanks for your reply. I'll attach next time.

I'll accept what you say, but even environment
variables that are in my windows environment are not
in the environment of programs run under "run". By
environment, I mean that if you type set in a cmd
window, you get the windows environment. Practically
none of those environment variables that appear when I
type "set" in the cmd window are in programs run under
the cygwin "run" command. Also, this behaviour was not
observed in cygwin before I updated it recently. I
looked at the source of "run" and see all it does is a
CreateProcess with NULL in the environment pointer
which I thought simply passes "run"'s environment to
the newly created process. I put a printf in run.c
just before the CreateProcess call and got the HOME
environment variable and printed it. The value that is
printed is correct. The HOME environment variable in
the new process is incorrect.

Any ideas?

Thanks,

-jeff hardy
