Long paths with ../../../../ throughout

[Jon Grant <jg at jguk dot org>]

Hello

gcc -o t -###  test.c
Any easy way to evaluate and reduce command lines? Consider this:

/usr/lib/gcc/i486-linux-gnu/4.3.3/../../../../lib/crt1.o

Is actually the same as: /usr/lib/crt1.o  -- which is much clearer!

I'm using Ubuntu 9.04.

Cheers, Jon
