SDCC with Cypress FX2LP - Issues? Limitations?

I just got my brand new EZUSB dev kit from Cypress which comes with an
eval version of the  Keil compiler and many handy examples which I got
running in no time flat with the Keil tools.  My question is regarding
the SDCC compiler.  Since SDCC likely does not directly support all of
the features of the FX2LP can anyone tell me the limitations for its
use on this particular platform?  I'm having some trouble converting
the examples to build and run using SDCC.  Is it pretty straightforward
to use once I get going, or is this just the tip of the iceberg in
terms of headaches?  Can anyone point me to info using SDCC with FX2LP?

Not surprised it is a professional tool

Why would you want to use SDCC whey you already have a perfectly good
compiler. You don't get better than the Keil for 8051.

As I understand it the eval version is only good for 4K of code.  In my
project I am the only developer, so I want to know if there is a good
reason to spend the money on the full version of Keil.

A quick google brought this up which is worth a perusal...
<http://hpsdr.org/archives/openHPSDRyahoo.pdf>

I used SDCC with the EZUSB-FX without any hassles. I didn't use anything 
above and beyond the standard 8051 except for the extra SFRs in the 
device. For example, the 2nd DP wasn't used except when hand-coding some 
assembler when trying to optimise performance.

It works.
It is the best 8051 compiler available.
It has a very good simulator/debugger
It has lots of support

There is a lot more to 8051 variants than just changing the header
files.

Don't get me wrong I want to use it.  Do you happen to know the cost
for license for one developer?
