+# These are essentially workarounds for Meson/Windows/MSVC.  Unfortunately,
+# Meson's default_library option doesn't support shared and static builds very
+# well.  In particular, it's often necessary to define different symbols for
+# static and shared builds of libraries so that symbols can be exported.  To
+# work around this, default_library=both isn't supported on Windows.  On other
+# platforms with GCC-like compilers, we can support both because symbols can
+# safely be exported in the same way (giving them default visibility) in both
+# static and shared builds.
