[Bug preprocessor/18502] New: trigraphs don't work with -std=gnu99

[rwxr-xr-x at gmx dot de]

Hello,

$ echo '??-' | gcc -P -E -trigraphs -std=gnu99 -trigraphs -
<stdin>:1:1: warning: trigraph ??- ignored, use -trigraphs to enable
??-
$

That shouldn't happen. Apparently -trigraphs is ignored with -std=gnu99. Weird.
