I wrote on this a quite a while ago and it seems very popular, so I thought I would write an update
I decided to include some of the files, to make it easier to use.
The first file is temper-1.0.tgz. I got this from the good looking guys over at www.relavak.com.
Here it is here temper-1.0.tgz
I downloaded it, and extracted it with 'tar zxvf temper-1.0.tgz'
Then I downloaded temper.c, which is my modified code.
I copied the temper.c file into the temper-1.0 directory.
Then I ran 'make'.
It produced and executable called 'temper'
Here is the compiled 32 bit version temper_32bit
And the compiled 64 bit version temper
