Avoid trigraph warning #139

Closed ndmitchell closed 5 years ago

ndmitchell commented 5 years ago

For reasons not entirely clear, when compiling Alex with Bazel I get a warning about an invalid trigraph (it's probably doing its own CPP stuff or using its own options). It's not a fatal warning, but seems easy enough to avoid in this instance.
