It works for me with on 2.4.19-rmk6

    $ uname -a
    Linux winder 2.4.19-rmk6 #2 Sun Feb 2 12:28:26 MST 2003 armv4l unknown
    $ /usr/arm-linux-uclibc/bin/arm-uclibc-gcc
    -Wall -Os foo.c -o foo
    $ ./foo 
    50 / 10 = 5
so my initial guess is either 2.5.59-rmk1 is busted, or perhaps
the libgcc division code is using floating point and you didn't
enable the kernel fpu emulator.  dunno.
