  27  *   case, unless one has manually modified the attributes).
  28  *

  30  *   sections (read-only data and exports, respectively) have the same
  31  *   attributes, the .edata section is appended to the .rdata section.
  32  *   Otherwise they are kept separated, unless an explicit /MERGE is used.
