check libimsg too patch from Anna "CyberTailor"

always append LDFLAGS and CFLAGS Initial patch from Anna "CyberTailor", tweaked by me (drop guessing_* and always append CFLAGS)

add -T timeout to gg; don't let the regress test hang

try to preserve as much as possible CFLAGS and LDFLAGS from env but still try to autodetect with pkg-config if they aren't provided. Passing CFLAGS/LDFLAGS from the command line will still override the guessed ones.

explain the OpenBSD bit

don't log too much by default

test macro expansion too

show macro usage in the example

gracefully shut down fastcgi backends we need to delete the events associated with the backends, otherwise the server process won't ever quit. Here, we add a pending counter to every backend and shut down immediately if they aren't handling any client; otherwise we try to close them as soon as possible (i.e. when they close the connection to the last connected client.)

don't let CGI scripts inherit our stderr our stderr could have been sent to the logger process, so it may be invalid. Furthermore, in the future we may want to capture also the stderr of the processes.

reset fcgi array in free_config otherwise path, port and/or prog could become an invalid pointer.

fix seccomp filter for ppc64le before we matched ppc64le as ppc64 (which is big ending I presume), so the seccomp filter would always kill gmid #4 related
