Answers for "dnl configure.ac"

dnl configure.ac

dnl is an m4 macro that discards all input that follows it on the same line (including the newline). # doesn't mean anything in m4, so it ends up in the target (Makefile?), in which it acts as a comment.

So the key difference is that dnl is a comment in the original source, whereas # becomes a comment in the generated file.
