I don't know about your environment, but for me (cross from
x86_64-linux to cris-elf) that causes a:

I've committed the following as obvious, following the pattern
of the other files including internal.h, after observing
all-libbacktrace (i.e. built for the host) complete.
libbacktrace:
* backtrace.c: #include <sys/types.h>.
