Another compatibility feature is
.Dv COMPAT_SVR4_32,
which allows the execution of 32-bit SVR4 binaries on a machine
with a 64-bit kernel. This requires
.Dv EXEC_ELF32
and
.Dv COMPAT_NETBSD32
options as well as
.Dv COMPAT_SVR4.
It is configured the same way as
.Dv COMPAT_SVR4
but uses the /emul/svr4_32 directory instead of /emul/svr4. But
typically, /emul/svr4_32 can be made to point to /emul/svr4 if the
operating system donating the libraries has support for both 32-bit
and 64-bit binaries.
