* frame.h (SIZEOF_FRAME_SAVED_REGS): Report an error if macro

already defined.

From 2000-08-25 Stephane Carrez <Stephane.Carrez@worldnet.fr>:
* stabsread.c (define_symbol): A parameter ('R'), a local ('r'),
or a reference ('a') can be in a pseudo register.
* infcmd.c (do_registers_info): Must take into account the pseudo
registers to print their value.
(registers_info): Likewise.
* stack.c (frame_info): Likewise.
* frame.h (SIZEOF_FRAME_SAVED_REGS): Save the pseudo registers.
