+ * config/i386/tm-i386.h: Add forward declaration of `struct value'.
+ (FIX_CALL_DUMMY): Redefined to call i386_fix_call_dummy.
+ (i386_fix_call_dummy): Add prototype.
+ * i386-tdep.c (i386_fix_call_dummy): New function based on the
+ code from the old FIX_CALL_DUMMY macro.

* procfs.c, remote.c: Eliminate use of PARAMS from these files.
