While working on another series, I noticed that c-lang.h does not need to include parser-defs.h. This patch makes this change, and fixes up the two .c files that needed this include. Tested by rebuilding. gdb/ChangeLog 2020-11-25 Tom Tromey <tom@tromey.com> * d-lang.c: Include parser-defs.h. * rust-lang.c: Include parser-defs.h. * c-lang.h: Do not include parser-defs.h.
