in reply to Kill C style comments

I highly suggest you pick up a copy of Jeff Friedl's "Mastering Regular Expressions", where this example is discussed in great length. The Final answer is: 
s{(?:"(?:\\.|[^"\\])*")|(?:/\*[^*]*\*+(?:[^/*][^*]*\*+)*/)}{}g

[download]
Which nicely "unrolls the loop" for double-quote-aware comment removal. Pretty slick, huh? Check the book out ASAP!



Code is (almost) always untested.

    That still won't handle '/*' (single quotes) which is in fact valid C, equal to ('/' << 8) + '*'
