BSDINSTALL is defined in make/host.cfg.in as
BSDINSTALL=@INSTALL@
@INSTALL@ is generated by autoconf's standard macro AC_PROG_INSTALL, which
is widely used in almost any autoconf/automake configured package. In case
there is really something wrong with it, then it must be considered a bug
in autoconf.
I can see a doubious fragment in AC_PROG_INSTALL, which is used when no
appropriate bsd-install is found.
Finally Ralf saw a problem with the find on solaris which I also saw and
fixed.

dnl Note: $host_os should probably *not* ever be used here to
|
|
dnl determine if host supports System V IPC calls, since some
|
|
dnl (e.g. FreeBSD 2.x) are configured by default to include only
|
|
dnl a subset of the System V IPC calls. Therefore, to make sure
|
|
dnl all of the required calls are found, test for each call explicitly.
|
|
dnl
|
|
dnl All of the calls use IPC_PRIVATE, so tests will not unintentionally
|
|
dnl modify any existing key sets. See the man pages for semget, shmget,
|
|
dnl msgget, semctl, shmctl and msgctl for details.
