The source snippet at the bottom used to compile with gcc
up to including
4.0.0,
and stopped compiling with 4.0.1. The most recent
version I tried was
gcc version 4.1.0 20051202
and it failes.
This also compiles fine with a number of other compilers,
including Intel-C++, Comeau-C++, Visual-C++, Sun-CC.
The source:
-------------------------------------------------------------
class A { friend class B; B *b; };
main() { A a; }
-------------------------------------------------------------
gcc-4.1 -S -O friend-opaque.cc
friend-opaque.cc:1: error: ISO C++ forbids declaration of 'B' with no type
friend-opaque.cc:1: error: expected ';' before '*' token
-------------------------------------------------------------
