[Nel] gcc and non-ANSI

[Vincent Caron]

I'm using gcc/g++ 2.95.3, and it seems that it doesn't like anonymous structures
(see gcc output below). I read that it's definitively not a standard feature,
and was orginally a MS VC++ extension, that was more or less adopted by others.
Seems that the gcc guy didn't approved it, but I didn't checked in depth. I
guess others are using the egcs c++ (1.1.2) frontend ?
I personnaly don't approve being able to acces a member without naming the
structure ...
