+       Clean up scanners a bit.
+       * src/flex-scanner.h (FLEX_NO_OBSTACK): New macro that blocks obstack
+       definitions so gcc won't warn when obstack_for_string is unused.
+       * src/scan-code.l: config.h and system.h are already #include'd by
+       scan-code-c.c, so get rid of them here.
+       * src/scan-gram.l: Likewise.
+       * src/scan-skel.l: Likewise, and use flex-scanner.h without obstack
+       definitions rather than duplicating the rest of it.
+       * src/scan-gram-c.c, scan-skel-c.c: #include "system.h".
