    Thank you. Actually I wonder how bash is built without SIGCHLD/ SIGCLD.
I have scanned bash source (but not thoroughly enough, I guess) and I see
nothing. It looks like bash can be compiled with DJGPP with SIGCHLD/SIGCLD.
Actually I'm trying to build pdksh in
DJGPP but I don't have an idea whether or not I should take out the source
about job control (that require SIGCHLD/SIGCLD).
