re PR preprocessor/39647 (Syntax checks in #line not quite right)
libcpp:
PR preprocessor/39647
* directives.c (check_eol): Add parameter expand.
(do_undef, parse_include, do_line, do_linemarker, do_ident,
do_pragma_once, do_pragma_system_header, do_ifdef, do_ifndef,
do_else, do_endif, do_assert, do_unassert): All callers changed.
Pass true from do_line, false elsewhere.
gcc/testsuite:
* gcc.dg/cpp/line7.c: New test.
