A little bit more on the changes

--parms-in-bank1 (ds390/mcs51) -- when this option is set the compiler will
pass parameters using bank1 registers. The first parameter will be passed 
in DPTR:b:a (as before) the second parameter onwards 8 more bytes will be
passed in b1_0 thru b1_7... i.e. with this option set we can pass up to
12 bytes of parameter in registers. The libraries will need to be rebuilt
with this option , the interrupt service routines will save and restore 
this bank ...using bank1 in a interrupt service routine will have BAD
consequences .. I have fixed up the optimized assembler routines in the 
library to work with this option as well . 

--protect-sp-update (ds390) will disable interrupts when updating ESP:SP.

The DS390 port can now allocate DPTR1 to live ranges , currently only
for pointer variables (size <= 3), infrastructure added for more DPTRS.

Dhrystone for ds390 now stands at 504 .
