I expected that this would happen.  Such long names are becomming more 
and more common, particularly for C++ projects with huge rafts of 
class libraries.

The next question is if this broken 'ar' can be replaced with one that 
works.  Fixing the broken 'ar' might also require replacing the 
linker.

While this system is historically significant it is not significant in 
terms of current usage.  It does not make sense for libtool to provide 
a workaround unless that workaround is assured to work.
