[Freedos-cvs] kernel/hdr portab.h,1.26,1.27

[<bar...@us...>]

Update of /cvsroot/freedos/kernel/hdr
In directory sc8-pr-cvs1.sourceforge.net:/tmp/cvs-serv6495/hdr

Modified Files:
	portab.h 
Log Message:
Define I386 and I186 more cleanly.
Add (UWORD) casts to silence the compiler.
Optimize (head*sector) to secs_per_cyl
Add BORLANDC to compiler list and simplify startup printf to one message.
#pragma enable_message(130) for Watcom C causes it to behave a little more
like Borland in terms of warnings.
