I read this posting with interest, because I have often wanted an assembly output
listing similar to what Borland produces with the -S option, with each C
statement interleaved with the assembler code it generates.  Unfortunately, the
above options do not do this, as was claimed -- I only get assembler, binary, and
cross references; no C source.  Is it possible to get interleaved C and assembly
output?

I have actually managed to do this, but only by the tedious procedure of
modifying the source to look like this:

a = 3; asm("#a = 3;);
b = a; asm("#b = a;);

etc.  There must be a better way.
