Bug in startxwin.bat after installing with setup.exe in win98SE

[Thomas Chadwick]

I hate to jump into the middle of a religious argument (which this is 
turning out to be) but it seems to me that a plausible solution would be to 
urge the maintainers of the cygwin setup program to define a CYGWIN_ROOT 
environment variable for us.  Cygwin setup is already putting stuff in the 
registry, isn't it, so why not this?

You could then modify the startxwin.bat and startxwin.sh scripts such that 
they don't attempt to assign CYGWIN_ROOT if it already has a value.
