[Bug preprocessor/33063] New: C++ preprocessor warns about /* in //-comments starting with //*

[trick at icculus dot org]

As a minimal example, take the following 3-line file:

--- 8< ---

/*
//*
*/

--- 8< ---

Preprocessing this file with -Wall (using either g++ or cpp directly) results
in the warning '"/*" within comment'.  This only happens if the surrounding /*
*/ pair is present.

(I discovered this in some code that uses separators like this:

//*****************************************..

Commenting these off with /* */ results in the bogus warnings.)
