When I made modification for m68k/netbsd, I noticed syscalls.c include macro 'ENOTSUP'. Even though this macro is defined for solaris and so on, this is not defined for NetBSD. In case of Linux, there's a definition for this in '/usr/include/bits/errno.h' to be same as 'EOPNOTSUPP'. For NetBSD, what is the best way to define it? Kiyo
