Dear all, what are your explanations for these incompatible circumstances: 1. /usr/include/libutil.h originates with FreeBSD. humanize_number(3) and flopen(3) appear in prototypes. 2. /usr/lib/libutil.a is clearly Glibc. Only login, pty, and wtmp related symbols. 3. /usr/include/utmp.h is again Glibc. Prototypes for logwtmp, and so on. Where have you pushed humanize_number() and flopen()?
