Ah, that's the reason. But given my recent discomfort about
unmaintainable code, look at it again:
# if BOOST_WORKAROUND(__HP_aCC, <= 33900)
template<bool cond, typename T> struct enable_if;
template<bool, typename T> struct enable_if;
Does this really makes sense? Shouldn't we just keep one version with
names for template parameters? AFAICS this should work for all compilers
and it could be a general boost coding guideline to always provide names
for template parameters. Comments?
