  /* NOTE: The new architecture variable is named \`\`current_gdbarch''
     so that macros such as TARGET_ARCHITECTURE, when expanded, refer to
     the current local architecture and not the previous global
     architecture.  This ensures that the new architectures initial
     values are not influenced by the previous architecture.  Once
     everything is parameterised with gdbarch, this will go away.  */
  struct gdbarch *current_gdbarch;

"this will go away" refers to "is named current_gdbarch".
