This is causing a compilation warning on Windows:
https://buildfarm.postgresql.org/cgi-bin/show_stage_log.pl?nm=3Dwhelk&dt=3D=
2019-07-19%2001%3A41%3A13&stg=3Dmake

"C:\buildfarm\buildenv\HEAD\pgsql.build\pgsql.sln" (Standardziel) (1)
->
"C:\buildfarm\buildenv\HEAD\pgsql.build\zic.vcxproj" (Standardziel)
(72) ->
 src/timezone/zic.c(2401): warning C4804: '-' : unsafe use of type
  'bool' in operation
[C:\buildfarm\buildenv\HEAD\pgsql.build\zic.vcxproj]

Buildfarm members using VS like whelk complains about that, and I can
see the warning myself.
