cv/cv: Modified Makefile to install source into /usr/share/sendmail and
to only make netbsd-proto.cf. (all other .cf files were made, but never
installed anywhere. So why burn CPU building files we don't use. Added
a target called "other" to make all other .cf files.)
this version of sendmail tries to use sysconf() if the _SC_* macros
are defined in unistd.h. We have the macros but not
the function. A temporary "fix" has been made to avoid
the issue.
