Jakub Jelinek <jakub at gcc dot gnu.org> changed: What |Removed |Added ---------------------------------------------------------------------------- CC| |jakub at gcc dot gnu.org --- Comment #7 from Jakub Jelinek <jakub at gcc dot gnu.org> --- E.g. in ISO C99, 6.10.3.2, you can read that #s is replaced by a single preprocessing token, but the mere fect that L immediately precedes it doesn't make it a part of the same preprocessing token. For wide character literals, the L needs to be part of the same preprocessing token as the "string" after it.
