>Description:
	For some reason the version of gdb installed with NetBSD is built with
	a crippled version of readline, and not the one that normally comes
	with gdb.  The current version is severely crippled in several ways, 
	not least of which are:

	1) Inability to support long command lines (more than 1000 characters).
	2) Inability to do completion on symbol names.

	
>How-To-Repeat:
	Try to get gdb to accept the following command:
	set args -nostdinc++ -nostdinc++ -v -I/home/rearnsha/gnusrc/egcs/libstdc++-v3/include/std -I/home/rearnsha/gnusrc/egcs/libstdc++-v3/include/c -I/home/rearnsha/gnusrc/egcs/libstdc++-v3/libsupc++ -I/home/rearnsha/gnusrc/egcs/libstdc++-v3/include -I../libio -I/home/rearnsha/gnusrc/egcs/libstdc++-v3/libio -I/home/rearnsha/gnusrc/egcs/libstdc++-v3/libmath -I../include -iprefix /work/rearnsha/gnu/egcs/gcc/../lib/gcc-lib/arm-netbsd/2.97/ -isystem /work/rearnsha/gnu/egcs/gcc/include -isystem /work/rearnsha/gnu/install/arm-netbsd/bin/include -isystem /work/rearnsha/gnu/install/arm-netbsd/lib/include -D__GNUC__=2 -D__GNUC_MINOR__=97 -D__GNUC_PATCHLEVEL__=0 -Dunix -Driscbsd -Darm32 -D__arm32__ -D__arm__ -D__NetBSD__ -D__unix__ -D__riscbsd__ -D__arm32__ -D__arm32__ -D__arm__ -D__NetBSD__ -D__unix -D__riscbsd -D__arm32 -Asystem=unix -Asystem=NetBSD -Acpu=arm -Amachine=arm -D__CHAR_UNSIGNED__ -D__STDC_HOSTED__=1 -g -Wall -Wno-format -W -Wwrite-strings -Winline -D__ARM_ARCH_3__ -D__APCS_3!

	Groan with frustration when you find that after 1000 characters your
	terminal goes haywire and you are completely unable to debug your
	program.

	Compile a program with the symbol foo_wibble_wombat_xywssdjfkl
	in it.  At the gdb prompt type 
		break foo_<tab>
	then get extremely frustrated when completion does not work and
	you have to type the whole symbol in by hand.

	
>Fix:
	Use GNU readline when building gdb.
