/*
 * The original SVR3 ABI states:
 *
 * Application Constraints
 * As described above, libsys provides symbols for applications. In a few cases,
 * however, an application is obliged to provide symbols for the library.
 *
 * extern char **environ;
 *     Normally, this symbol is synonymous with environ, as
 *     exec(BA_OS) describes.  This isn't always true, though, because
 *     ANSI C does not define environ.  Thus, an ANSI C-conforming
 *     application can define its own environ symbol, unrelated to the pro-
 *     cess environment.  If the application defines environ and intends it
 *     to have the System V Interface Definition, Third Edition semantics, it
 *     must also define _environ so that the two symbols refer to the same
 *     data object.
 *
 * The ABI description implies that the process environment should use
 * _environ and that nothing in libc should make reference to the unadorned
 * "environ" symbol.  This way, an application can define and use a symbol
 * named "environ" for its own purposes without affecting the actual
 * process environment.
