Document the fact the MSCL8 compiled kernels don't work.
...
Don't initialize BSS variables anymore -- now done by the memset in main.c
Removed obsolete BYTE cfgCSYS_fnam[NAMEMAX]; config variable.
Changed cfgInit and cfgInitTail to pointers, adjusted some code to work
with them.

for some time) and the assignment in config_init_buffers() was
wrong (screwed up fnodes, so that buffers overlapped fnodes...).

From: Eric Luttmann <ecl@users.sourceforge.net>
...
Fix for multisegmented device drivers: If there are multiple device
drivers in a single driver file, only the END ADDRESS returned by the
last INIT call should be the used. It is recommended that all the
device drivers in the file return the same address.
This fixes a load problem with DUSE.
