[Bug preprocessor/36453] New: PR36320 breaks boost

[mueller at gcc dot gnu dot org]

testcase:

=== Cut ===
#if !defined(BOOST_PP_IS_ITERATING)

#elif BOOST_PP_ITERATION_DEPTH() == 1
#endif
=== Cut ===

error: missing binary operator before token "("


from reading the PR36320, this behaviour doesn't seem to be intended. It was
intended to only add a check for non-null argument.
