122             using some MS magic. I found some useful information on this web page:
123             http://msdn2.microsoft.com/en-us/library/y4h7bcy6(VS.80).aspx. According to the
124             information there, using __declspec(dllexport) without "extern" we have a
125             definition; with "extern" we have a declaration. The settings here override the
126             setting in pcre.h (which is included below); it defines only PCRE_EXP_DECL,
127             which is all that is needed for applications (they just import the symbols). We
128             use:
129              
130             PCRE_EXP_DECL for declarations
131             PCRE_EXP_DEFN for definitions of exported functions
132             PCRE_EXP_DATA_DEFN for definitions of exported variables
133              
134             The reason for the two DEFN macros is that in non-Windows environments, one
135             does not want to have "extern" before variable definitions because it leads to
136             compiler warnings. So we distinguish between functions and variables. In
137             Windows, the two should always be the same.
138              
139             The reason for wrapping this in #ifndef PCRE_EXP_DECL is so that pcretest,
140             which is an application, but needs to import this file in order to "peek" at
141             internals, can #include pcre.h first to get an application's-eye view.
142              
143             In principle, people compiling for non-Windows, non-Unix-like (i.e. uncommon,
144             special-purpose environments) might want to stick other stuff in front of
145             exported symbols. That's why, in the non-Windows case, we set PCRE_EXP_DEFN and
146             PCRE_EXP_DATA_DEFN only if they are not already set. */

1149             the characters so that they always use the ASCII/UTF-8 code when UTF-8 support
1150             is enabled. When UTF-8 support is not enabled, the definitions use character
1151             literals. Both character and string versions of each character are needed, and
1152             there are some longer strings as well.
1153              
1154             This means that, on EBCDIC platforms, the PCRE library can handle either
1155             EBCDIC, or UTF-8, but not both. To support both in the same compiled library
1156             would need different lookups depending on whether PCRE_UTF8 was set or not.
1157             This would make it impossible to use characters in switch/case statements,
1158             which would reduce performance. For a theoretical use (which nobody has asked
1159             for) in a minority area (EBCDIC platforms), this is not sensible. Any
1160             application that did need both could compile two versions of the library, using
