c) recvmsg() must get MSG_CMSG_CLOEXEC set
d) F_DUPFD_CLOEXEC should be used instead of F_DUPFD, and so on
-- We never use the XDG version of basename(). glibc defines it in

+- We never use the POSIX version of basename() (which glibc defines it in

+ The only reason to include libgen.h is because dirname()
is needed. Everytime you need that please immediately undefine
basename(), and add a comment about it, so that no code ever ends up

- Use the bool type for booleans, not integers. One exception: in public
headers (i.e those in src/systemd/sd-*.h) use integers after all, as "bool"
are always defined after more global ones. Thus, our local
definitions will never "leak" into the global header files, possibly
altering their effect due to #ifdeffery.

+- To implement an endless loop, use "for (;;)" rather than "while
+ (1)". The latter is a bit ugly anyway, since you probably really
+ meant "while (true)"... To avoid the discussion what the right
+ always-true expression for an infinite while() loop is our
+ recommendation is to simply write it without any such expression by
+ using "for (;;)".
