# Shell script to create proper links to machine-dependent files in

# 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.
#       --gxx-include-dir=DIR specifies directory to put g++ header files 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.
