 *  comments (unfortunately) cannot be placed on the same line as #defines,
 *  because this causes errors in the assembler.
 *
 *  Most (if not all) of these values must be considered frozen, as
 *  they are used by product in the field and are assumed by tight assembly

/*
 *  System Call ID codes.
 *
 *  These ID codes are used both in the MULTI <--> server protocol and the
 *  monserv <--> monitor protocol.
 *  
 *  When using the Green Hills cross libraries, these codes are passed as the
 *  first argument to the function __syscall_ghs in the appropriate indsyscl.*
 *  module of the libraries.  The codes are 32-bit values, with the low 16 bits
 *  containing the call number, and the high 16 bits containing the
 *  argument count (including the first argument, the code number itself).
 *
 *  When implementing System Call support in a debug server, these codes
 *  are stored as the first argument in the argument list pointed to by
 *  the XTRA_STAT syscall.args field.
 *  
 *  Codes that have an argument count of zero are handled internally by the
 *  target or its debug server and must not be passed to MULTI via XTRA_STAT.
 *  For these calls, the argument list is defined at the time the call number
 *  is assigned, and the target knows how many arguments there should be by
 *  looking at the call number itself.
 *
 *  Note that function names beginning with '__' don't really exist; they
 *  are called internally by the libraries or debug servers and do not
 *  correspond directly to any well-known system calls.
