Strange.

Kind of - the extended test case is in
libs/config/test/boost_no_exp_func_tem_arg.cxx

Everything in suffix.hpp is generic macro workarounds - it's not dependent
upon specific compilers just whether the appropriate macro is defined.

I think you are going to have to use a dirty workaround here: check for gcc
before using BOOST_EXPLICIT_TEMPLATE_TYPE(void)
 in this particular case.
