Yeah ... an isolated "/" inside the comment doesn't work either.

I poked at this for awhile and concluded that we probably cannot make
it work with a single regexp for "cppline". The right thing would
involve an exclusive start condition for parsing a cppline, more or
less like the way that /* comments are parsed in the <xc> start
condition. This is kind of a lot of work compared to the value :-(.
Maybe somebody else would like to take a crack at it, but I can't
get excited enough about it.
There are other deficiencies too in ecpg's handling of these things,
like the fact that (I think) comments are mishandled in #include
directives.
