I'm trying to compile an optimized version of the seti_boinc client on a Fedora Core 3 Test 1 system (GCC 3.4.1), but the compilation fails with:

... (many similar errors omitted)

All the errors are related to friend declarations, so the problem may be related to this: http://gcc.gnu.org/faq.html#friend
The GCC team has again "tightened" the compiler to reject sloppy code that was accepted in previous compiler versions.

I've been seeing the same error on FreeBSD 5.x ever since they switched to gcc 3.4.2. Unfortunately, since the 3.4.2 broke C++ ABI compatibility, I can't run my old BOINC/S@H client which was compiled with 3.3.3. I'd really appreciate a fix for this.
