* rendering/RenderObject.cpp:
(WebCore::RenderObject::showRenderObject):
(WebCore::RenderObject::showRenderSubTreeAndMark):
Add "#pragma clang" preprocessor macros to ignore this warning
since the code is only compiled for Debug builds.  Also add a
pragma for the pragma so older clangs don't complain about an
unkonwn pragma.

The fileExists() function will always return false on Windows,
if the filename parameter ends with a slash or backslash.

* platform/network/curl/CurlCacheManager.cpp:
(WebCore::CurlCacheManager::setCacheDirectory): Add slash after call to fileExists().
