Hmm, that's true. As long as the emulations are concerned,
only the syscalls matter. AFAICS, only generated init_sysent.c
has to be changed then. Instead of generating sequencies as:

#ifdef COMPAT_09
...
#else
...
#endif

it should generate appropriate

#if defined(COMPAT_09) || defined(COMPAT_FREEBSD)
...
#else
...
#endif

etc.

Shouldn't be too hard to implement. sys/kern/syscalls.conf
would have one more variable defined, say compatops_dep,
in the form as:

compatops_dep="freebsd:compat_09 ... hpux:compat_43" etc.

and makesyscalls.sh would be adjusted to generate proper
ifdefs. Thoughts ?
