# Create global symbol declarations, transfer vector, and
# linker options files for PerlShr.
#
# Processes the output of makedef.pl.
#
# Input:
#    $cc_cmd - compiler command
#    $objsuffix - file type (including '.') used for object files.
#    $libperl - Perl object library.
#    $extnames - package names for static extensions (used to generate
#        linker options file entries for boot functions)
#    $rtlopt - name of options file specifying RTLs to which PerlShr.Exe
#        must be linked
#
# Output:
#    PerlShr_Attr.Opt - linker options file which specifies that global vars
#        be placed in NOSHR,WRT psects.  Use when linking any object files
#        against PerlShr.Exe, since cc places global vars in SHR,WRT psects
#        by default.
#    PerlShr_Bld.Opt - declares universal symbols for PerlShr.Exe
#    Perlshr_Gbl*.Mar, Perlshr_Gbl*.Obj (VAX  only) - declares global symbols
#        for global vars (done here because gcc can't globaldef) and creates
#        transfer vectors for routines on a VAX.
#    PerlShr_Gbl.Opt (VAX only) - list of PerlShr_Gbl*.Obj, used for input
#        to the linker when building PerlShr.Exe.
#
# To do:
#   - figure out a good way to collect global vars in one psect, given that
#     we can't use globaldef because of gcc.
#   - then, check for existing files and preserve symbol and transfer vector
#     order for upward compatibility
#   - then, add GSMATCH to options file - but how do we insure that new
#     library has everything old one did
#     (i.e. /Define=DEBUGGING,EMBED,MULTIPLICITY)?
