+       * infptrace.c (KERNEL_U_ADDR_BSD):  Include a.out.gnu.h.
+       * i960-tdep.c, m68k-tdep.c, sparc-tdep.c, tm-i960.h,
+       tm-m68k.h, remote-nindy.c:  Change ext_format_XXX structs
+       to single structures rather than arrays; when passing
+       their address, use &.  This avoids trouble with bdead compilers.
+       * mcheck.c: Don't include <stdlib.h>; just declare "void abort();"
+       instead.  This avoids portability headaches.
+       * mips-tdep.c (mips_do_registers_info):  Only print FP regs if
+       asked to.
+       * source.c (open_source_file):  Avoid ANSI const bdeath by 
+       skipping declaration and then casting result value.
+       * tm-hp300bsd.h:  Clarify comment.
+       * utils.c (strstr):  Result is const char *; ANSI bdeath.
+       * xm-hp300bsd.h:  Define HOST_BYTE_ORDER.  Redefine INT_MIN,
+       since system include file defines it differently from "defs.h",
+       though the two are equivalent for our purposes.
+

        * tconfig/sun*4:  Remove warnings about system assembler.
