cppinit.c (init_standard_includes): The returned buffer is already malloc-ed.
* cppinit.c (init_standard_includes): The returned buffer
is already malloc-ed.
* gcc.c (add_prefix): Similarly.
* prefix.c (translate_name): Update to support clear buffer
ownership rules.
(update_path): Similarly. Be sure to free any newly allocated
key. UPDATE_PATH_HOST_CANONICALIZE takes only one argument.
(tr): New function.
* prefix.h (update_path): Update prototype and document.
* config/i386/xm-djgpp.h (UPDATE_PATH_HOST_CANONICALIZE): Clean
up and update to new buffer ownership rules.
* doc/gcc.texi (UPDATE_PATH_HOST_CANONICALIZE): Update.
