System: SunOS bombur.uio.no 5.8 Generic_108528-13 sun4u sparc SUNW,Ultra-5_10
Architecture: sun4
host: sparc-sun-solaris2.8

>Description:
-Wtrigraphs should warn about `//' comment lines that end with
`??/', since -trigraphs changes whether or not the next line is
taken to be part of the comment.
Also, when that is fixed, the the description of -Wtrigraphs
should mention this exception to the statement that trigraphs in
comments are not warned about.
>How-To-Repeat:
bash$ cat a.c
#include <stdio.h>
int main()
{
// multi-line comment ??/
puts("oops");
return 0;
}
bash$ gcc -trigraphs -Wtrigraphs a.c
bash$ ./a.out
bash$
