GCC 2.95.2

[c958179@student.dtu.dk]

I am using gcc-2.95.2 to compile a c++ program. The program has been
compiled and run with a egcs-1.1.2 compiler before.But when I try to
compile the same program with gcc-2.95.2 I get errors like:

ANCI C++ forbids declaration 'xxxx' with no type.
and
field 'xxxx' has incomplete type.

What is the meaning of these errors?

Are there something wrong with the program or with the compiler?

Thank you in advance.

Sc.
