+ * While the ISO C Standard does not require that function pointers be
+ * interconvertible to void *, widely-used compilers such as gcc and clang
+ * do such conversion implicitly and automatically on some platforms without
+ * issuing any warning.
+ *
+ * For Solaris Studio, that is not the case.  An explicit type cast is needed
+ * to suppress warnings on that particular conversion.
