It seems to me that you don't want to use -b, not -e -- you can compile 
the file you would load with -b in the query of -e, i.e.

-e "......, compile(boot)"

instead of -b boot.

That really is only suitable for Un*x, and is a holdover from the old 
days. We certainly don't try to do anything clever with what the 
`current directory' is on Windows -- as I said, this is probably fixed 
by Windows, unless you start ECLiPSe in unusual ways, e.g. inside a bash 
shell in cygwin. Also, the `home directory' is also probably not defined 
when you start ECLiPSe using normal Windows methods.

You can see the code that does this in toplevel.pl (compile_rc/0), and
it is done when the query toplevel:toplevel is called -- i.e. within the 
-e if you follow Joachim's suggestion.
