	gdb            : config.in configure.in i386-linux-nat.c 
	gdb/config/i386: nm-linux.h 

Log message:
	2000-03-05  Mark Kettenis  <kettenis@gnu.org>
	
	Allow GDB to run on Linux 2.0 again.
	* config.in: Add HAVE_PTRACE_GETREGS.
	* configure.in: Check if <sys/ptrace.h> defines PTRACE_GETREGS.
	* configure: Regenerated.
	* config/i386/nm-linux.h (CANNOT_FETCH_REGISTER,
	CANNOT_STORE_REGISTER): New defines.
	* i386-linux-nat.c (have_ptrace_getregs): New variable.
	(PTRACE_XFER_TYPE, CANNOT_FETCH_REGISTER, fetch_register,
	old_fetch_inferior_registers, CANNOT_STORE_REGISTER,
	store_register, old_store_inferior_registers): Copied over from
	`inptrace.c' as a temporary measure.
	(fetch_regs, store_regs, fetch_fpregs, store_fpregs):
	Conditionalize on HAVE_PTRACE_GETREGS.  Define stubs if
	HAVE_PTRACE_GETREGS isn't defined.
	(fetch_regs): Reset `have_ptrace_getregs' if ptrace call fails
	with EIO.
	(fetch_inferior_registers, store_inferior_registers): Fall back on
	the method use in `infptrace.c' (by calling
	old_fetch_inferior_registers and old_store_inferior_registers) if
	`have_ptrace_getregs' isn't set.
