+ * We define this wrapper for two reasons. Firstly, later versions of
+ * DEC C add linkage information to certain functions, which makes it
+ * tricky to use them as values to regular function pointers.
+ * Secondly, in the EDK2 build environment, the strcmp function is
+ * actually an external function (AsciiStrCmp) with the Microsoft ABI,
+ * so we can't transparently assign function pointers to it.
+ * Arguably the latter is a stupidity of the UEFI environment, but
+ * since the wrapper solves the DEC C issue too, let's just use the
