* emultempl/pe.em(make_import_fixup): change signature to
        take asection as well as arelec; we need this for proper
        error reporting.  Only call pe_create_import_fixup() if
        there is no attempt to add a constant addend to the reloc;
        otherwise, report error condition.
        * pe-dll.c(pe_walk_relocs_of_symbol): change signature,
        since final argument is a pointer to make_import_fixup().
        Change call to cb() to match make_import_fixup() signature.
        (make_import_fixup_mark): make buffer_len unsigned.
        * pe-dll.h: change signature of pe_walk_relocs_of_symbol.
2001-09-12  Charles Wilson  <cwilson@ece.gatech.edu>
        * ld.texinfo: add verbose documentation for auto-import
        direct-addressing workaround, to compliment the terse
        error message.
