src/cmd/ksh93/data/signals.c includes two checks for the JOBS identifier; if it is not defined then the interactive shell's background job signal messages for SIGINT and SIGPIPE are empty. The cause was that the "jobs.h" header, which defines that ID, was not #included in signals.c. This commit adds that #include. (ksh 93u+, ksh 93v- and ksh2020 all have this bug as well.) Before: $ sleep 30 & [1] 86430 $ kill -s INT "$!" [1] + sleep 30 & $ After: $ sleep 30 & [1] 86445 $ kill -s INT "$!" [1] + Interrupt sleep 30 & $
