That fixed the problem.
I changed the parameter for both .exw and .ex files to read "%0" instead of 
%1 (so that the whole command line is passed, just in case), and the file now
properly opens.

Either I somehow messed that up - but I really can't see when - or there are
some double quotes to add in the strings the install script uses to define file
associations. I'll let omeone with more experience with this language to look
into it.

There's still a standing bug when two filenames have the same length and differ
by accented characters. They are considered different even though they may differ
by case only. As I said, same_name() in scanner.e needs some smarts to deal with
this.

RBIL v61 reports that the DOS function AX=#65A2 (ASCIZ country dependent
filename capitalization) is hardly functional, which would require some low level
work using the filename uppercase table directly. Can anyone infirm this? It
would really help making the code more compact (it wouldn't be overly complex
otherwise).
