+ * config.host: Set the shell variable host_can_use_collect2.
+ Set it to yes by default, and to no for alpha*-dec-*vms*,
+ i[34567]86-*-mingw32*, and powerpc-*-beos*.
+ * configure.ac: Set and substitute the shell variable collect2.
+ Give an error if use_collect2 is yes and host_can_use_collect2 is
+ no.
+ * Makefile.in (COLLECT2): Rename from USE_COLLECT2. Change all
+ uses. Initialize to @collect2@.
+ (STAGESTUFF): Remove $(USE_COLLECT2).
+ * config/alpha/x-vms (USE_COLLECT2): Don't set.
+ * config/i386/t-mingw32 (USE_COLLECT2): Likewise.
+ * config/rs6000/t-beos (USE_COLLECT2): Likewise.
+ * config/pa/t-pa64: Remove commented out USE_COLLECT2.
+ * configure: Regenerate.
