The file is cfgrtl.c without underscore. When you have a "to..." somewhere,
you need to have a "...here" somewhere else:
* cfgrtl.c (delete_insn): ...here. Change return type to void.
The hunk for delete_insn contains a line with trailing TABs and spaces.

OK for stage1 when it re-opens (modulo the above nits). Nice cleanup!
