Many lines from a macro?

[Peter Wentworth]

Can a C macro replacement ever result in more than one output line from
the preprocessing stage?

I am using the SUN assembler which first uses the C preprocessor.
The C macro

#define FOO       jmp label;\
                  nop;\
              label:

expands to this output:       jmp label;  nop;  label:

But the assembler insists that the label starts on a new line,
so this is not acceptable.  Is there some magic that will 
yield three separate lines of macro output, instead of one?

I don't think this can ever cause problems in C, but I suspect
there other languages that would benefit from using a general
standardized C preprocessor as a front end.  Was there ever any
notion among the ANSI committee that things like preprocessing
features could be included on grounds of 'general usefulness',
rather than 'useful only to C'?
