167 a range of consecutive warning numbers
168 <letter>
170 a predefined set
171 default setting is
173 "+a-4-6-7-9-27-29-30-32..42-44-45-48-50-60-66-67-68"
174 -warn-error <list>

190 Enable or disable colors in compiler messages
191 The following settings are supported:
193 auto use heuristics to enable colors only if supported

202 "dumb", and that isatty(stderr) holds.
203 If the option is not specified, these setting can alternatively
205 be set through the OCAML_COLOR environment variable. -er‐
