I posted a patch for building gdb-4.17 on Red  Hat 5.1 (which is using
glibc-2.0.7) some weeks   ago. Please note,   you cannot build  gdb on
recent  hacker   kernels   (2.1.x) due   to  removal    of   the  file
<linux/debugreg.h> which glibc's <sys/debugreg.h> still refers to.

Hope this helps,

gdb/ChangeLog:

1998-08-15  Manfred Hollstein  <manfred@s-direktnet.de>

	* i386v4-nat.c: Add #include <sys/reg.h> on Linux with GNU libc.
	* gdbserver/low-linux.c: Likewise.
	(PTRACE_PEEKUSR): Map to PTRACE_PEEKUSER with GNU libc.
	(PTRACE_POKEUSR): Map to PTRACE_POKEUSER with GNU libc.

	* config/i386/nm-linux.h (NO_PTRACE_H): Undefine with GNU libc.
	(NO_SYS_REG_H): Don't define with GNU libc.
