Renaming the defines would be problematic since my library shares a 
configuration file with libtool's libldtl and configures once rather 
than twice.  I am not interested in modifying libldtl to use my own 
naming scheme.

Lucky for me, the header files only require four definitions, one 
definition is usually disabled, and another maybe could be elminated 
with a bit of work.  Only one of those definitions (WORDS_BIGENDIAN) 
is from autoconf!
