(define-skeleton my-c-conditionalize
  "Conditionalize a piece of code with cpp stuff."
  "CPP var to use: "
  \n "#ifdef " str
  \n _
  \n "#endif /* " str " */" \n)

And then (using transient-mark-mode) select the region of code you want
to conditionalize and do M-x my-c-conditionalize RET MACRO_NAME RET
