Port uIP-LPC2129 from (expensive)CrossWorks to (free)WinARM

I almost achieve to port the uIP to WinARM, however when linking some
errors show up. I found a solution in the thread

http://en.mikrocontroller.net/topic/58281

so I used the crt0.s and LPC2129-RAM/ROM.ld that are included in WinARM
dist, but errors still appear. The thread says that I should edit
syscals.c by hand, but that file is in folders for the SAM mcu, not in
LPC folders. I guess I might copy it to my work folder and edit it to
see what happens. If my makefile is needed plese tell me to copy into
the post

Thanks
