+ * Forward-decl-only glib.h shim, on libqemu-cxx's PRIVATE include path
+ * BEFORE the system glib path.
+ *
+ * Why: libqemu's generated typedefs.h is wrapped in extern "C" by
+ * libqemu/libqemu.h, and qemu-plugin.h does `#include <glib.h>`. Modern
+ * glib.h has C++ template inline functions (g_steal_pointer, ...) that
+ * fail with "template with C linkage" inside extern "C". qbox's plugin
+ * API surface only references @c GArray and @c GByteArray as opaque
+ * pointers, so opaque forward-decls are sufficient — and shadowing real
+ * glib for the libqemu-cxx target only is safe because nothing in qbox
+ * C++ uses real glib internals.
