Indeed, it looks like errno.h is not included ('errno' was not declared) as well as unistd.h ('getcwd' was not declared).

It seems that the following block was ignored (top of dwarf.c):

#if linux || APPLE || FreeBSD
#include	<signal.h>
#include	<unistd.h>
#include	<errno.h>
#endif

I bet neither of the three are defined for some reason.
