Subject: Specify an explicit underlying type for this enum to fix Windows
X-Git-Url: https://granicus.if.org/sourcecode?a=commitdiff_plain;h=dd5dcddd4129abf56d69a0d5b380cc7c31ef07ee;p=clang

Specify an explicit underlying type for this enum to fix Windows
buildbots.

On Windows targets, enums always get an underlying type of 'int', even
if they have wider enumerators. (This is non-conforming, but it's
effectively part of the target ABI.)
