Comment # 3 on bug 94231 from Emil Velikov

Are you sure about the removal of "include sys/sysmacros.h" ? Afaics
include/sys/types.h includes the posix/sys/types.h with the latter still having
the include.

Bth I'm not sure if things can explode with the unconditional include, imho
it's better to keep things as documented.

I.e. if the _BSD_SOURCE define does not help, then either glibc needs to be
fixed or the manuals should be updated (the glibc fold might have some
suggestions) ?
