I'm having a bit of a problem getting started in using interrupts in C
with LPC2129 and GCC.
The search function seems to be broken at this moment so I'm starting
a new thread.

My problem is, there are so many interrupt sources, how can I tell
from within the IRQ or FIQ routine where my interrupts are originating
from?
Would be great to see some example of interrupt code that uses
multiple interrupt sources. Start a New Thread

Take a look at the gcc_and_ucosii.zip file in the files area, or
available at:

the PDF

http://www.ovro.caltech.edu/~dwh/ucos/project_AR1803.pdf

should have enough to get you started.
