    Hi, I try to compile a bootloader "vivi" for my strongARM embedded
    system. However, when i run "make"

    /opt/host/armv4l/bin/armv4l-unknown-linux-gcc
    -I/root/cheong/gsl/linuette/vivi/include -I/opt/host/armv4l/include/
    -Wall -Wstrict-prototypes -O2 -fPIC -fomit-frame-pointer -mapcs-32
    -mshort-load-bytes -msoft-float -c -o init/main.o init/main.c

    as: ????? `-mapcs-32'
    make: *** [init/main.o] Error 1

    So what is the problem from "-mapcs-32"? As I refer to arm-opion for my
    gcc-2.95.2
    http://web.umr.edu/~gnudoc/single/gcc-2.95.2/gcc.html#SEC22

    It should supported this options!

    My gcc compiler is "armv4l-unknown-linux-gcc" and my Makefile under the vivi/arch/Makefile is like this:

    --------------------------------------------------------------
    # Select CPU dependent flags. Note that order of declaration is
    important;
    # the options further down the list override previous items.
    #
    # Note! For APCS-26 YOU MUST HAVE AN APCS-26 LIBGCC.A
    #
    apcs-y :=-mapcs-32

    # This selects which instruction set is used.
    arch-y :=
    arch-$(CONFIG_CPU_32v4) :=-march=armv4

    # This selects how we optimise for the processor.
    tune-y :=
    tune-$(CONFIG_CPU_ARM920T) :=-mtune=arm9tdmi
    tune-$(CONFIG_CPU_SA1100) :=-mtune=strongarm1100

    CFLAGS +=$(apcs-y) $(arch-y) $(tune-y) -mshort-load-bytes
    -msoft-float
    AFLAGS +=$(apcs-y) $(arch-y) -mno-fpu -msoft-float

    ifeq ($(CONFIG_CPU_32),y)
    PROCESSOR = armv
    TEXTADDR = 0x00000000
    endif
    LDSCRIPT = arch/vivi.lds.in

    ifeq ($(CONFIG_ARCH_SA1100),y)
    MACHINE = sa1100
    TEXTADDR = 0x00000000
    endif

    ifeq ($(CONFIG_ARCH_S3C2400),y)
    MACHINE = s3c2400
    ifeq ($(CONFIG_S3C2400_GAMEPARK),y)
        TEXTADDR = 0x00000000
        ifeq ($(CONFIG_S3C2400_GAMEPARK_OSSWITCH),y)
          TEXTADDR = 0x00100000
        endif
        ifeq ($(CONFIG_S3C2400_GAMEPARK_ON_RAM),y)
          TEXTADDR = 0x0C000000
        endif
    else
       TEXTADDR = 0x00000000
    endif
    endif

    ... ....
