88 using some MS magic. I found some useful information on this web page:
89 http://msdn2.microsoft.com/en-us/library/y4h7bcy6(VS.80).aspx. According to the
90 information there, using __declspec(dllexport) without "extern" we have a
91 definition; with "extern" we have a declaration. The settings here override the
92 setting in pcre2.h (which is included below); it defines only PCRE2_EXP_DECL,
93 which is all that is needed for applications (they just import the symbols). We
94 use:
95 
96   PCRE2_EXP_DECL    for declarations
97   PCRE2_EXP_DEFN    for definitions
98 
99 The reason for wrapping this in #ifndef PCRE2_EXP_DECL is so that pcre2test,
100 which is an application, but needs to import this file in order to "peek" at
101 internals, can #include pcre2.h first to get an application's-eye view.
102 
103 In principle, people compiling for non-Windows, non-Unix-like (i.e. uncommon,
104 special-purpose environments) might want to stick other stuff in front of
105 exported symbols. That's why, in the non-Windows case, we set PCRE2_EXP_DEFN

612 the characters so that they always use the ASCII/UTF-8 code when UTF-8 support
613 is enabled. When UTF-8 support is not enabled, the definitions use character
614 literals. Both character and string versions of each character are needed, and
615 there are some longer strings as well.
616 
617 This means that, on EBCDIC platforms, the PCRE2 library can handle either
618 EBCDIC, or UTF-8, but not both. To support both in the same compiled library
619 would need different lookups depending on whether PCRE2_UTF was set or not.
620 This would make it impossible to use characters in switch/case statements,
621 which would reduce performance. For a theoretical use (which nobody has asked
622 for) in a minority area (EBCDIC platforms), this is not sensible. Any
