Re: Undefined symbol "_Unwind_GetIPInfo" on FreeBSD 6.0

[David Pratt <fairwinds at eastlink dot ca>]

Hi David. There is no libunwind that I am aware of for this platform. I 
see a libunwind from gnu.org for download though I am not clear that it 
is designed for i386-freebsd platform. Any advise on getting around this 
is appreciated.

Regards,
David
