Numerous changes including the following:
+ DEBUG_EARLY_START re-added (Eric Valette)
+ segment register initialization (Aleksey/Quality Quorum)
+ heap size use correction
+ more debug printk's
+ increased heap size.
Now works with grub boot on all systems I have access to including
desktops and a laptop. This is with the i386-rtems tools.
Neither i386-rtemself nor netboot produces a working executable.
