Is USE_RTC automatic when using m-a to build the zaptel modules for 
kernel 2.6?

The rather long Wiki description mentions the HZ setting amongst many 
other things, is it safe for me to leave this in my guide or would it be 
best not having it there?

I'm considering that the person reading this may have tweaked their 
kernel for specific hardware or network options, and/or they may have 
had an older gcc when they built their kernel.  E.g. I had built my 
kernel on a faster box with gcc 3.x, and copied it to a box with a 
500MHz CPU running Asterisk, which has gcc 4.x.  Then I compiled the 
module on the slower box.  The kernel rejected the module, presumably 
because of the newer gcc.  Rebuilt everything on the same box, and 
module was accepted.

However, I'm sure there are plenty of people out there who will be lucky 
enough to just run the commands listed below.

Nonetheless, I've summarised the possible faults at the bottom of my 
guide and advised people that they can skip some steps.
