Hello again

A short while ago I reported my experiences with cross compiling with msc5.1;

I had tools/menu fall over. After close inspection it turned out that the
declaration of the external variables in menu1.s did not pu them in DGROUP
but in _TEXT. This caused the wrong address to be picked up just before calling
the kernel. The solution is to add .bss or .data at the start of the program
before the .extern of relevant symbols, otherwise all symbols are assumed to
be in .text (the mode the assembly start in by default). I see it as a problem
with menu1.s which one is lucky to get away with using asld, I am not sure how
the TC users fair here (Any comments from those people? Earl?).

Now there is the last proble, where login.c falls over after reading the
userid. At that point the system is up, the file-systems mounted etc. This
is a harder one because there could be influence from the four .s modules
in kernel and those are too big for easy debugging. I would appreciate any
help here.
