44cf0a17a1 fix and enable i386 support 
This gives ~5K size reduction with bc3.1.
Today no one uses pre-i386 CPUs so there is no good
reason against having an extra optimization.

8187fd8153 disk: fix sectors count truncation for CHS [fixes #10] 
LBA_to_CHS() uses geometry taken from BIOS, but LBA_Transfer()
was using the geometry from VBR. This caused "count" variable
to underflow over unsigned long, then corrupting the entire
DOS memory with the large read.

This patch makes LBA_to_CHS() to return the geometry to caller,
so that the calculus do always match.

Thanks to @ecm-pushbx and @andrewbird for helping to
nail this down.

f4c9691ef5 fix watcom check 
WATCOM var may be defined in autoexec.bat, but this doesn't
mean the user wants to build with watcom.
Check the COMPILER="WATCOM" instead.
