Fix this port so that it can find crt0.o in /usr/lib/aout on recent -current systems. Fix the definition of the preprocessor symbol __FreeBSD__. It had been defined as "2=3". Implement support for weak symbols. This solves the "___error" undefined problem on -current systems. Default to -fsjlj-exceptions even for C programs. This is needed because a few modules in libgcc are built with -fexceptions turned on, and the default style of exception support causes croakage. I tried a make buildworld on a recent -current system by adding the following to /etc/make.conf: CC=/usr/local/bin/gcc28 -B/usr/local/lib/gcc-lib/i386-unknown-freebsd3.0/2.8.1/ CXX=/usr/local/bin/g++28 -B/usr/local/lib/gcc-lib/i386-unknown-freebsd3.0/2.8.1/ It got pretty far along before dying. The death occurred when building our old native libstdc++, almost certainly because of header file incompatibilities. Another obstacle for make world is that this port doesn't currently build a PIC version of libgcc (libgcc_pic.a).
