The COMPAT_14 option does exist, but it pulls in the system calls that
were changed post-1.4. The options required include EXEC_AOUT and COMPAT_14,
and old a.out libraries need to be moved into /emul somewhere (I don't
remember where exactly -- /emul/aout/usr/lib perhaps). That would allow
for the running of a.out NetBSD executables on an ELF NetBSD system. I
guess you could move most of /usr into /emul/aout and run the compiler
That, of course, assumes that the old 1.4 tree was still present.
