Is COMPAT_LINUX required for COMPAT_20?

Hi there!

NetBS xxx.core.de 4.0 NetBSD 4.0 (BEAVER) #0: Sun Dec 16 
14:36:33A

The pkgsrc/security/f-prot packages fails to run due to compat issues:

root@:~#/usr/pkg/bin/f-prot -report=foo /var/mail/
Virus scanning report  -  31 March 2008 @ 14:39

F-PROT ANTIVIRUS

ktrace shows:

 21884      1 f-prot   RET   fcntl 0
 21884      1 f-prot   CALL

 21884      1 f-prot   RET   __sysctl 0
 21884      1 f-prot   CALL  compat_20_fstatfs(7,0xbfbfdd3c)
 21884      1 f-prot   RET   compat_20_fstatfs -1 errno 78 Function not 
implemented
 21884      1 f-prot   PSIG  SIGSYS SIG_DFL


Is that an issue in the Linux-compat?

Thank you!
