It looks like there are a few ports that have problems with our gcc
compiler on sparc64.

1) Some of them complaing about missing libstdc++ symbols:

/libexec/ld-elf.so.1: budgie/budgie: Undefined symbol "_ZN9__gnu_cxx18__exchange_and_addEPVii"

/usr/local/lib/libAtlasObjects-0.6.so: undefined reference to `__gnu_cxx::__exchange_and_add(int volatile*, int)'
/usr/local/lib/libvarconf-1.0.so: undefined reference to `_ZN9__gnu_cxx18__exchange_and_addEPVii@GLIBCXX_3.4'

This seems to be a MD libstdc++ symbol that we may not be adding
properly on sparc.

2) A couple of ports are failing like this:

log.c:21894: warning: incompatible implicit declaration of built-in function 'strchr'
{standard input}: Assembler messages:
{standard input}:23537: Error: Illegal operands
{standard input}:23597: Error: Illegal operands

which makes me suspect that gcc is emitting opcodes that binutils
cannot assemble.

3) there are a number of ports that are failing at runtime due to
segfaults.

Is anyone interested in investigating?

Kris
