Unfortunately it changes nothing in regard to my problem - whether all 
"o+/-" or only some of them (I tried changing only "outer" pair or only 
"inner" pairs) are capital "O+/-" the error remains:

The problematic .def file:

Line 275 is the one right before {Returns} - with only "@*".

Changing "o+/-" to "O+/-" changes table to itemize, but nothing more...

The "solution" I've found - to put "." in between them (or actually any 
character, but dot is converted to "smallexample", thus not visible) 
changes NOTHING in the whole file - just adds something between "@end 
whatever" and the following commands. Here I've placed an 'a' right 
after "o-" and compared to "normal" output:

I know that the reason for error seems stupid - that there must be 
"something" after "@end table" or "@end itemize", before "@*", but I'm 
pretty certain that's the real reason - for example if I take sprintf.c 
- that does NOT cause any problems - and remove all text after last "O-" 
that is before RETURNS the exact same problem happens again...

4\/3!!
