Subject: Drop the warning about __attribute__((may_alias)) being used
X-Git-Url: https://granicus.if.org/sourcecode?a=commitdiff_plain;h=4659e1e2e06983e4de77040315537aa86984cec8;p=clang

Drop the warning about __attribute__((may_alias)) being used
on a non-type declaration, as GCC permits it on variables too.
This fixes PR8635.
