Suppress to GCC warning with multi-line comment

[hsbt]

https://rubyci.s3.amazonaws.com/debian11/ruby-master/log/20250404T003003Z.log.html.gz shows compilation warning with main.c.

main.c: In function ‘Init_rbs_extension’:
main.c:24:3: warning: multi-line comment [-Wcomment]
   24 |   // grep -o 'INTERN("\([^"]*\)")' ext/rbs_extension/parser.c \
      |   ^

I replaced that comment with /* */ style. I'm not sure this is good for that.

Another solution.
sh (of course also bash) continues to the next line after |, so this command is valid.

grep -o 'INTERN("\([^"]*\)")' ext/rbs_extension/parser.c |
    sed 's/INTERN("\(.*\)")/\1/' |
    sort -u |
    wc -l
