[Bug libstdc++/64276] would be better to use __cpp_exceptions rather than __EXCEPTIONS to determine whether exceptions are available

--- Comment #2 from Jakub Jelinek <jakub at gcc dot gnu.org> ---
A Compilation Process is "Eligible" if it is done using GCC, alone or
with other GPL-compatible software, or if it is done without using any
work based on GCC. For example, using non-GPL-compatible Software to
optimize any GCC intermediate representations would not qualify as an
Eligible Compilation Process.

so I think you're wrong on this, the runtime exception can be used even when
code is compiled by other compilers, if they aren't based on GCC.
