Summary: The LibFunc::Func enum holds enumerators named for libc functions. Unfortunately, there are real situations, including libc implementations, where function names are actually macros (musl uses "#define fopen64 fopen", for example; any other transitively visible macro would have similar effects). Strictly speaking, a conforming C++ Standard Library should provide any such macros as functions instead (via <cstdio>). However, there are some "library" functions which are not part of the standard, and thus not subject to this rule (fopen64, for example). So, in order to be both portable and consistent, the enum should not use the bare function names. The old enum naming used a namespace LibFunc and an enum Func, with bare enumerators. This patch changes LibFunc to be an enum with enumerators prefixed with "LF_". (Unfortunately, a scoped enum is not sufficient to override macros.) These changes are for clang.
