Thanks for the reply, responses in the text below. For
some conciseness, I'll cut out parts of my original
message.

Yeah, I haven't bothered much with UNIX on my desktop
since my main machines were Solaris and linux until
recently. I have a MacBook but need to migrate a
ton of software off Windows, much of it which can't
unless I get "parallels". This programming project
arose because of the need to reformat a Windows flat
data file. I may have to fall back to copying the data
to MacOS X, running the script under UNIX, and copying
the results back to Windows. Sigh.

Nope. Isn't that special! But cygwin's upgrade says where it thinks
it is and it isn't. The check.txt file is attached.

I'm not convinced that it is harmless. e.g. I have a CAD program
installed and it is in the path. It may need that to locate
configuration or setup files. If I remove it all, and it doesn't
work or breaks something, I have to worry about typos when I put
it back in. Too many blanks, quotes, etc., to do it frivolously.
Wouldn't be a problem on UNIX where I could save a config file
and put it back...

I don't remember why I have g77 installed. As I recall, it might have
been added as a cygwin package, but can't recall for sure. And not
having cygwin experience, it doesn't just jump out at me.
And it is a serious question. Full blown UNIX machines which I and my
staff have run, are capable of having installed multiple packages,
even multiple versions, with no ill effect. Windows still suffers
from being designed as a single user operating system, unlike UNIX
which was designed as a true multiuser and multitasking operating
system. Things trip over each other all the time. Sigh.
Currently, I need the Bourne shell. But I want gcc and g77 later.
I am successfully using a Bourne shell script from Windows, but it
is very wounded. After running the script a few time, I get can't
forks, and Zone Alarm shuts down and starts up. Then I have to
reboot to get a couple of more successful script runs. Quit annoying
to someone used to scripting on Solaris.
I guess tomorrow I have a look to see if g77 can be removed, and
have a shot at killing the PATH (ugh!). Any other ideas are welcome.
Thanks, John
