libcpp: Fix up -fdirectives-only handling of // comments on last line not terminated with newline [PR100646] As can be seen on the testcases, before the -fdirectives-only preprocessing rewrite the preprocessor would assume // comments are terminated by the end of file even when newline wasn't there, but now we error out. The following patch restores the previous behavior. 2021-05-20 Jakub Jelinek <jakub@redhat.com> PR preprocessor/100646 * lex.c (cpp_directive_only_process): Treat end of file as termination for !is_block comments. * gcc.dg/cpp/pr100646-1.c: New test. * gcc.dg/cpp/pr100646-2.c: New test.
