Yes; at this point I don't think it improves anything sufficiently to spend
more time on it.
Forgive me a digression, but having now actually used libbacktrace, I have
the following questions.
1.

I now realize that a less intrusive approach is available: just provide
replacement filenames.h, dwarf2.h in a separate directory and pick up those
headers for a standalone build. In replacement dwarf2.h, include system

Ah, I still should have typedef'ed those types to enum tags when IN_GCC. I've
verified the following patch bo

I've amended configure.ac to provide a new configuration flag
('--enable-standalone') and add -DIN_GCC to EXTRA_FLAGS unless that flag is
given. Previously I've misread grep output and thought that IN_GCC

I'm not sure I understand the question. Is it possible to link
libbacktrace statically? Sure. That is what happens
