Indeed, I overlooked that, but my opinion remains that we shouldn’t play 
with fixed vs free form considerations here.
So the options I can see are:
  - handle the locus in get_kind; we do it a lot already in matching 
functions, so it wouldn’t be different here.
  - implement a variant of gfc_match_char without space gobbling.
  - use gfc_match(...), which is a bit heavy weight to match a single 
char string, but otherwise would keep things concise.

My preference goes to the third option, but I’m fine with either of them 
if you have a different one.
