During build on powerpc64, there's a warning:
parser.cc: In function 'int skip_remarks(HighParser&, InputStream&, char&)':
parser.cc:64:2: warning: case label value is less than minimum value for type
64 | case -1: // should be EOF!
powerpc64 uses unsigned char by default.
This (along with my other patches) should be upstreamed, but I don't have an account on upstream's GitLab.
