Appearances are deceptive, it won't handle trigraphs. For instance, try:
??' (trigraph for ^) and your code thinks it is in_char.

What's worse, on systems where char isn't signed and EOF == -1, it will
fail to see EOF (suggestion: don't use a char to compare against EOF).

Another cake that is hard to digest (let alone the goto's, it was baked
in only 15 minutes) 8-).

P.S. What's the benefit of having a separate program strip off comments anyway?
