Subject: Move two Darwin-specific hacks into #ifdef __APPLE__. These were stat'ing
X-Git-Url: https://granicus.if.org/sourcecode?a=commitdiff_plain;h=7efb8af368309b5a2e5f9fa4df6da136d1c5ac54;p=clang

Move two Darwin-specific hacks into #ifdef __APPLE__. These were stat'ing
nonexistent Darwin-specific files on every module build.
