Chris, there is now a problem with the generated uninstall
script (I don't know if it was caused by your changes).

When I ran the uninstall script from the Windows menu a
dos window showed up. It contained the following message.

All files in directory will be deleted!
Are you sure (Y/N)?

That is a little scary, would it really delete ALL files?

This message is being printed by the Win 95 del
command when it is passed a directory instead
of a file. The cause of this problem is deep
down in setup.c.

A directory like usr/bin/ in the tar file was
getting converted to C:\Cygwin\usr\bin, so
setup.c thought it is was a file not a directory.
When setup.c goes to write out the command to
delete a file or directory, it checks to see
if the name ends with a \ char.

I do not know if this ever worked, but it is
broken now so I whipped up a patch for the
problem. This patch will append a \ char on
the end of a filename that setup.c is processing.

This also changes the directory where the uninstaller
will cd to internally and turns the install.bat
file into a windows style name so it can be deleted.

This patch also adds /usr/local/bin to the default
PATH set in cygwin.bat. Users that install programs
with autoconf will be installing into /usr/local
by default so it should be on the PATH.

Oh yeah, this patch also fixes a little compiler warning
(the void ** bit).
