Here is the make file by the way...
# Hey Emacs, this is a -*- makefile -*-
#
# WinARM template makefile
# by Martin Thomas, Kaiserslautern, Germany
# <eversmith@heizung-thomas.de>
#
# based on the WinAVR makefile written by Eric B. Weddington, Jörg
Wunsch, et al.
# Released to the Public Domain
# Please read the make user manual!
#
#
# On command line:
#
# make all = Make software.
#
# make clean = Clean out built project files.
#
# make program = Download the hex file to the device, using lpc21isp
#
# (TODO: make filename.s = Just compile filename.c into the assembler
code only)
#
# To rebuild project do "make clean" then "make all".
#
# Changelog:
# - 17. Feb. 2005 - added thumb-interwork support (mth)
# - 28. Apr. 2005 - added C++ support (mth)
# - 29. Arp. 2005 - changed handling for lst-Filename (mth)

# it will preserve the spelling of the filenames, and gcc itself does
# care about how the name is spelled on its command-line.
