* 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.
