> Hopefully backtrace.c is honoring HAVE_GETIPINFO and we just need to
figure out why it's not getting set right... weird.
I think the cause is in this report:
{{{
config.log

configure:11674: result: yes
}}}
I patched CFLAGS a bit to see more of the compilation test. I think
removing the "-c" option would be the proper test.
I also made this test:
{{{

function-declaration -lgcc_eh conftest.c

(unwind-dw2.o)
ld: warning: object file compiled with -mlong-branch which is no longer
needed. To remove this warning, recompile without -mlong-branch:
/usr/lib/crt1.o
}}}
I actually don't know what's libgcc_eh.a good for – but it somehow works…
Here is a bit more documentation from some files as indicated:

This contents of confdefs.h is revealed a bit later. Presumingly the test
for Unwind_GetIPInfo contained only the lines up to
{{{
| #define HAVE_GETIPINFO 1
}}}
I think I've done with the examination of the *compilation* buffer in GNU
Emacs now, so I'm going to change my patch and I'll try to remove the "-c"
and see what I'll get – in one or two days…
