/*  asm.h

 *

 *  This include file attempts to address the problems

 *  caused by incompatible flavors of assemblers and

 *  toolsets.  It primarily addresses variations in the

 *  use of leading underscores on symbols and the requirement

 *  that register names be preceded by a %.

 *

 *  Authors: Ralf Corsepius (corsepiu@faw.uni-ulm.de) and

 *           Bernd Becker (becker@faw.uni-ulm.de)

 *

 *  NOTE: The spacing in the use of these macros

 *        is critical to them working as advertised.
