# Options: --srcdir=DIR		specifies directory where sources are.
# 	   --host=HOST		specifies host configuration.
#	   --target=TARGET	specifies target configuration.
#	   --build=TARGET	specifies configuration of machine you are
#				using to compile GCC.
#	   --prefix=DIR		specifies directory to install in.
#	   --local-prefix=DIR	specifies directory to put local ./include in.
#	   --exec-prefix=DIR	specifies directory to install executables in.
#	   --with-gnu-ld	arrange to work with GNU ld.
#	   --with-gnu-as	arrange to work with GAS.
#	   --with-stabs		arrange to use stabs instead of host debug format.
#	   --with-elf		arrange to use elf instead of host debug format.
#	   --nfp		assume system has no FPU.
#
# If configure succeeds, it leaves its status in config.status.
# If configure fails after disturbing the status quo, 
# 	config.status is removed.
