/SHARE_GLOBALS
       /SHARE_GLOBALS
       /NOSHARE_GLOBALS (D)

    Controls whether the initial extern_model is shared or not
    shared (for those extern_models where it is allowed). The initial
    extern_model of the compiler is a fictitious pragma constructed
    from the settings of the /EXTERN_MODEL and /SHARE_GLOBALS.

    The default value is /NOSHARE_GLOBALS, which has the following
    effects:

    o  When linking old object files or object libraries with newly
       produced object files, you might get "conflicting attributes
       for psect" messages, which can be safely ignored as long as
       you are not building shareable libraries.

    o  The /noshare_globals default makes building shareable
       libraries easier.
