6.1 Binary File Support

Binary file support can be turned off when you run “configure” by specifying the --disable-binary option. This will cause admin to refuse to create an SCCS file whose “e” flag is set (see Flags). The admin program would normally do this if the user requested it via the -b option or if it discovered that the file could not safely be stored in the normal sccs file format.

This setting can be overridden with the environment variable CSSC_BINARY_SUPPORT; for a description of how to use this environment variable, see Environment Variables.

If you use cssc with support for encoded SCCS files turned off, encoded files will still be handled; cssc will just refuse to create a new one. This provides as great a degree of interoperability with other implementations of sccs as possible.
