Yes, that seems like a better name, as far as I understand how the macro 
is used.  In any case, it needs a comment to specify its semantics.  The 
comment needs to be clear which parts of the semantics relate to "the ABI 
for this glibc as a whole" versus "the ABI for this particular compilation 
using this glibc and the particular choice of long double made with the 
current compilation options".
