I suppose you meant to write "\\" for every "\".

Then the first call is not ok for path_rel, because the
2nd argument is expected to be a relative file spec
in Unix-notation. The second call will return  c:\a\b\f.

This will not work. The return value will be always the same.
__FILE__ refers to the file, where you refer to __FILE__.

Of course, my intention is not to create a variable for each
directory in question, nor for each file in question.

Probably my examples would be better readable as:
$1= path_rel( __FILE__,"../some_modes_from_xy/");
autoload("fir_mode",$1+"firmode.sl");
autoload("sec_mode",$1+"secmode.sl");
...
