+/* 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. However, when compiling for Virtual Pascal, things are done
+differently, and global variables are not used (see pcre.in). */
