+Subject: [PATCH] Support ICU 76.1 build
+ https://bugs.webkit.org/show_bug.cgi?id=282120
+
+Reviewed by Yusuke Suzuki.
+
+In ICU 76.1 an additional macro `U_SHOW_CPLUSPLUS_HEADER_API` was added to
+control visibility of the C++ API within ICU. Set this value to `0` since WebKit
+wants to only use the C API.
