Don't use a custom wrapper macro around __has_include (bug 25189).
This causes issues when using clang with -frewrite-includes to e.g., submit the translation unit to a distributed compiler. In my case, I was building Firefox using sccache. See [1] for a reduced test-case since I initially thought this was a clang bug, and [2] for more context. Apparently doing this is invalid C++ per [cpp.cond], which mentions [3]: > The #ifdef and #ifndef directives, and the defined conditional > inclusion operator, shall treat __has_include and __has_cpp_attribute > as if they were the names of defined macros. The identifiers > __has_include and __has_cpp_attribute shall not appear in any context > not mentioned in this subclause.
