+ @brief Implements log function.
+
+    PaUtil_SetLogPrintFunction can be user called to replace the provided
+	DefaultLogPrint function, which writes to stderr.
+	One can NOT pass var_args across compiler/dll boundaries as it is not
+	"byte code/abi portable". So the technique used here is to allocate a local
+	a static array, write in it, then callback the user with a pointer to its
+	start.
+
+    @todo Consider allocating strdump using dynamic allocation.
+    @todo Consider reentrancy and possibly corrupted strdump buffer.
