Sorry, but this is normally an English mailing list, and you will
normally do better to ask your questions in English.  There are no
doubt German lists as well, but I don't know where they are.

I would expect to see that error message if I named a variable
"_Accum".  Names which begin with an underscore followed by a capital
letter are reserved for the implementation.  The name "_Accum" is used
by gcc as a keyword to implement a fixed-pointer accumulator.  This
follows a proposed standard for fixed-pointer arithmetic in C.

I don't know whether that answers your question.
