Right.
$ grep -A2 -B2 __unused * param_lex.c-#include <sys/cdefs.h> param_lex.c-#else param_lex.c:#define __unused param_lex.c-#endif param_lex.c-
I believe that <sys/cdefs.h> on FreeBSD defines __unused to __attribute__(unused), or something similar. This was probably generated by a patched flex for FreeBSD. freebsd-lex might generate the same output, I don't know.
So while I probably might be able to patch this via s/__unused/__unused_by_other_systems_but__FREEBSD__/ this might break on som Debian/FREEBSD port and it would be better to fix the according flex input.
Debian GNU/kFreeBSD uses __FreeBSD_kernel__, not __FreeBSD__, so it shouldn't affect anything as far as Debian goes. I don't know what Debian GNU/kFreeBSD includes in <sys/cdefs.h>; perhaps one of the porters could tell you.
I also wonder whether there is some hidden quirk in flex. It might be that this only happens in old versions of flex and I have to admit that I have no idea at all about flex and what I would have to do to.
If you apply the attached patch, and regenerate the C file using flex, the program should compile properly. At least on my amd64 system, the executable is built.
