--- Comment #8 from Alan Modra <amodra at gmail dot com> ---
>From what you've shown here, I would guess that your msdosdjgpp system headers
#define MAXPATHLEN to PATH_MAX somewhere.  That's wrong unless they also
provide a PATH_MAX definition.  PATH_MAX is usually defined in limits.h while
MAXPATHLEN is defined in sys/param.h.

So I could close this bug as not being a binutils problem, but GNU programs
should not have arbitraty limits like PATH_MAX so I'm going to fix objdump and
readelf.
