specs, respectively.

Corresponding GCC ChangeLog entry:

2002-11-19  Jason Thorpe  <thorpej%wasabisystems.com@localhost>

        * gcc.c (The Specs Language): Document spec functions.
        (static_spec_functions, lookup_spec_function)
        (eval_spec_function, handle_spec_function)
        (if_exists_spec_function, alloc_args): New.
        (execute): Abort if processing_spec_function is true.
        (do_spec_1): Hand off spec to handle_spec_function if %:
        is encountered.  If processing_spec_function is true,
        end any pending argument when the end of the string is reached.
        (main): Use alloc_args to allocate the initial argument vector.
        * gcc.h (struct spec_function): New.
        (lang_specific_spec_functions): New extern.

        * config/netbsd-elf.h (STARTFILE_SPEC): Add if-exists(crti%O%s).
        (ENDFILE_SPEC): Add if-exists(crtn%O%s).
        * config/alpha/netbsd.h (ENDFILE_SPEC): Likewise.
