// Purpose:       Provide extern char **environ as required by POSIX 1003.1
// Description:   C library definition and allocation of POSIX 1003.1 environ
// Usage:         You can override environ at startup if you wish simply
//                by redefining yourself. Setting the libc.h configuration
//                option is the intended method though.
