+building as one that does not use the string instructions
+@code{SMOVF}, @code{SCMPU}, @code{SMOVB}, @code{SMOVU}, @code{SUNTIL}
+@code{SWHILE} or the @code{RMPA} instruction.  In addition the mark
+tells the linker to complain if an attempt is made to link the binary
+with another one that does use any of these instructions.

+Note - the inverse of this option, @code{-mallow-string-insns}, is
+not needed.  The assembler automatically detects the use of the
+the instructions in the source code and labels the resulting
+object file appropriately.  If no string instructions are detected
+then the object file is labelled as being one that can be linked with
+either string-using or string-banned object files.
