gdb steps into glibc functions

[Michael Elizabeth Chastain]

Hi Marc,

Whoops, I didn't know you were on ia64.  Yeah, you can't just upgrade
to Red Hat Linux 9 for that.

	$ ldd /orc-2.1/usr/ia64-orc-linux/bin/ir_b2a
	libm.so.6 => /lib/libm.so.6 (0x40028000)
	libc.so.6 => /lib/libc.so.6 (0x4004a000)
	/lib/ld-linux.so.2 => /lib/ld-linux.so.2 (0x40000000)

Interesting, so the system libc.so.6 is providing the symbols,
so it would be delicate to take them out.  Good idea to leave
them alone!
