Some fine print
Added Makefile for the platform DLL's

Next step is to determine which sources for the swt.dll compile and
which do not. The 'blderrors' directory will be included in commits
in this fase to record the path leading to a building dll.

o Added make_odin32.mak
o Changed default target to compile the sources for swt.dll
o Using Odin32 SDK without any modifications
o Redirecting stderr to errors directory

Because we don't scatter yet, make_odin32.mak resides outside the working
directory and a proxy make_odin32.mak which includes the real one is generated
when gathering the sources.

Separated compiling from non-compiling sources for swt.dll
