+
+ * PORTING, TODO, config/README: Update to reflect below changes.
+
+ * configure.in: Replace MINIMIZE and --with-minimal-bfd with
+ --with-bfd-targets="target1,target2,..." and the special target
+ "all" to get the previous default behavior.
+ Figure out which architecture and backend .o files are needed from
+ DEFAULT_VECTOR, SELECT_VECS, and SELECT_ARCHITECTURES as set in
+ the .mt files. Define TDEFAULTS based on them, also.
+
+ * Makefile.in: Remove references to MINIMIZE.
+ * archures.c, targets.c: Ditto.
+
+ * config/*.mt: Define DEFAULT_VECTOR, SELECT_VECS, and
+ SELECT_ARCHITECTURES as variables rather than as -D arguments to
+ TDEFAULTS.
+
+ * config/a29k-coff.mt,alphaosf.mt, i386-sco.mt, i960-bout.mt,
+ i960-coff.mt (TDEFAULTS): Don't put the default vector in
+ SELECT_VECS manually; it's automatic now.
+
+ * config/i386-sco.mt (TDEFAULTS): Don't put &sco_core_vec in
+ SELECT_VECS manually; -DSCO_CORE does it automatically now.

+ (TDEFAULTS): Don't define BFD; not used.

+ consistently and maintainably.
+ * nlmcode.h (nlm_object_p): Expand comments about leaked memory
+ to note that the problem is even more serious than just leaked
+ memory. Replace goto with more traditional return.
