I send an identical patch (except the message of course) on May 15th. And
there were different solutions on the mailing list as well.

Michael, can we commit a fix for this, please?
main(a){char*c=/*    Schoene Gruesse                         */"B?IJj;MEH"
"CX:;",b;for(a/*    Best regards             my address:    */=0;b=c[a++];)
putchar(b-1/(/*    Chris            cc -ox -xc - && ./x    */b/42*2-3)*42);}
