CVS tags: HEAD
engine/32bit.h moved to arch/generic/machine.h
cache.c moved to arch/hppa/
cleanalign.c moved to engine/
Instead of linking arch/xy/machine.h an custom include path is used
engine.a engine.o main.o makes with engine/Makefile now
history.fs and startup.fs works for dos and unix now
environment variable osclass is set in envos.fs, wich is os-specific
supressed some warnings in main.c
