/* 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. */
