If I want to cross-compile - in Eclipse IDE I add "prefix "arm-linux-gnueabi- which translates to "arm-linux-gnueabi-gcc"

All this makes the package I am working on useless ( straight from the box) since it does not use the latest version of config.guess in the first place and has "configure" script with no code provisions to analyze the overgrown triplet.

initialize lowest to some arbitrary high number (or assign it to the 1st number in marks, and then just loop 4 times)
loop 5 times
    if the current number is less than lowest, re-assign lowest to it
repeat
