Subject: Add COMPAT_SVR4_NCR support for making the SVR4 emulation behave as
X-Git-Url: http://artulab.com/gitweb/?a=commitdiff_plain;h=a4b5ca493661d27adb039d9c2addfd13795ad56d;p=openbsd

Add COMPAT_SVR4_NCR support for making the SVR4 emulation behave as
NCR SVR4, currently this means that syscall#76 (rdebug) should return
ENXIO instead of issueing a SIGSYS.  Also removed svr4_conf.h no
longer used.
