additional realpath program

[Jaco Kroon]

Hello,

I've had a few occasions now where I would have liked to be able to get 
the absolute name of a file in a script, or for some other reasons (such 
as knowing on which partition my file is actually located - don't ask).  
Anyway, the attached program will allow for this, simply compile, give 
it a relative path and it'll give you the complete path.

Yes I'm aware that it is a very simple program but useful none the less.

Jaco
