*
|
|
* 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 %.
|
|
*
|
|
*
|
|
* NOTE: The spacing in the use of these macros
|
|
* is critical to them working as advertised.
