flex issue when compiling

[Mike Solomon]

Hey all,

I am working with flex 2.5.35 and I got the following error when compiling on 
my new MacBook Pro (OS X 10.6):

flex -Cfe -p -p -oout/lexer.cc lexer.ll
lexer.ll:606: multiple <<EOF>> rules for start condition longcomment
flex: fatal internal error, exec failed

Has anyone else seen this problem?  If so, is there a flag I could pass to flex 
that'll clear this up?  Should I be sending this to the flex list?

Thanks!
Mike
