Changed source layout to no longer have include directories, and adjusted eclipse project and makefile accordingly
Switched from make to SCons for building the project
Added SCons cache data (.sconsign*) to .gitignore
Corrected a problem in the SConscript file that caused all the object files to be generated in the source directory
Fixing some eclipse project settings to prevent unresolved type errors
Still fighting eclipse...
Added arch command line variable to scons for controlling which architecture to build. Defaults to 'i586' currently.
Made CROSS_TOOLS variable passable on the command line to scons, but will default to the contents of the environment variable
Fixed dictionary lookup bug that would cause scons to throw if the CROSS_TOOLS environment variable was not set
Merge branch 'scons'
