I considered the original comment in features.h to be the desired
behaviour! If I do not specify a *_SOURCE, then I want to have as many
symbols defined as possible, at least everything that shows up in one of
the usual standards (X/Open, recent POSIX, ISO C99, etc. etc.). If all
these things do not show up by default, then we would have to add a huge
number of #defines to all the man page synopsis sections. The *_SOURCE
macros were primarily intended to restrict the number of symbols defined
by default, not to extend it. The majority of programmers should *not*
have to use them.
