+# Including -rtlib=compiler-rt in pixman_LIBS is a BAD HACK: At least when compiling with Clang
+# -fsanitize=undefined on Linux x86-64, the generated code references __muloti4, which is an
+# extension provided by libclang_rt.builtins-x86_64.a runtime, but not by GCC's libgcc_s.so.1 (which
+# ultimately boils down to a bug in LLVM, I would say). I am not sure whether it should in general
+# work to mix uses of the (default on Linux, at least) GCC libgcc_s and LLVM's libclang_rt.builtins
+# runtime libraries in one process, but for this specific case of libcairo.so it appears to work
+# well: For one, the only symbol referenced by libcairo.so from the runtime library is __muloti4;
+# for another, at least in my LLVM build, lib/clang/12.0.0/lib/linux/libclang_rt.builtins-x86_64.a
+# is only provided as a static archive; so libcairo.so will only contain a "harmless" copy of
+# __muloti4 and not have a DT_NEEDED of any libclang_rt.builtins dynamic library that it would pull
+# in at runtime.
+# But passing -rtlib=compiler-rt into cairo's configure via the more obvious LDFLAGS would fail at
+# least when building with -fsanitize=address and -fsanitize=undefined, as then the executable
+# compiled by configure when "checking whether the C compiler works" would reference
+# _Unwind_Backtrace etc. that are provided by GCC's libgcc_s.so.1 but not by LLVM's
+# libclang_rt.builtins-x86_64.a (and whatever the reason for that inconsistency). So
+# -rtlib=compiler-rt must be passed just into the linking of libcairo.so, but not generally into
+# cairo's configure. And pixman_LIBS happens to offer that. (The -Wc is necessary so that libtool
+# does not throw away the -rtlib=compiler-rt which it does not understand.)
