22# Shell script to create proper links to machine-dependent files in
23# preparation for compiling gcc.
24#
25# Options: --srcdir=DIR		specifies directory where sources are.
26# 	   --host=HOST		specifies host configuration.
27#	   --target=TARGET	specifies target configuration.
28#	   --build=TARGET	specifies configuration of machine you are
29#				using to compile GCC.
30#	   --prefix=DIR		specifies directory to install in.
31#	   --exec-prefix=DIR	specifies directory to install executables in.
32#	   --with-gnu-ld	arrange to work with GNU ld.
33#	   --with-gnu-as	arrange to work with GAS.
34#	   --with-stabs		arrange to use stabs instead of host debug format.
35#	   --nfp		assume system has no FPU.
36#
37# If configure succeeds, it leaves its status in config.status.
38# If configure fails after disturbing the status quo,
39# 	config.status is removed.
