Alcyon-C, and compilers derived from the 'Portable' C compiler (at least)
allow direct insertion of assembly statements into the compiled code.
the syntax is:
	asm( " any string to put into .s file ");

The double quotes are mandatory, and the entire statement must appear on
a single line.  This is processed during pass 1 of the compiler.  Any
linkages to variables, etc., must be in conformance with the code
generated by your compiler (look at a .s file for examples).
