I have seen similar failures under FreeBSD, Solaris, and likely 
several other operating systems.  But if it works with the latest GNU 
binutils under Linux, that must be good enough for the rest of the 
world, no? ;-)

A continuing problem is that software developers are usually using the 
latest tools and have forgotten the shortcomings of the tools which 
were current just a few years ago.  I still remember when Linux's GNU 
ld required that the user specify libraries in a particular order so 
that the link could succeed.  Probably some of these systems are still 
in use.

On some systems, `ld' seems almost as trusting as `ar' and expects 
that the programmer knows what she is doing.
