2.11.90 build failure - Epiphany (OS X)

["Steve Przybylski" <p_monkey99 hotmail com>]

Building under Darwin 8.2.0 (OS X 10.4), gcc4.0...Epiphany 1.7.3 appears to 
be the latest victim of OSX's incomplete libc.  Build fails in ephy-debug.c, 
when it's unable to inlcude execinfo.h, which doesn't exist on OS X.  From 
what I've been able to find, it appears that backtrace() isn't implemented 
anywhere else in Darwin, so this may be a big issue.  I know that the best 
answer is "port glibc to Darwin"...but does anyone have any other thoughts?
