+/* This module contains global variables that are exported by the PCRE library.
+PCRE is thread-clean and doesn't use any global variables in the normal sense.
+However, it calls memory allocation and freeing functions via the four
+indirections below, and it can optionally do callouts, using the fifth
+indirection. These values can be changed by the caller, but are shared between
+all threads.
+
+For MS Visual Studio and Symbian OS, there are problems in initializing these
+variables to non-local functions. In these cases, therefore, an indirection via
+a local function is used.
+
+Also, when compiling for Virtual Pascal, things are done differently, and
+global variables are not used. */
