86 http://msdn2.microsoft.com/en-us/library/y4h7bcy6(VS.80).aspx. According to the
87 information there, using __declspec(dllexport) without "extern" we have a
88 definition; with "extern" we have a declaration. The settings here override the
89 setting in pcre2.h (which is included below); it defines only PCRE2_EXP_DECL,

91 use:
92 
93   PCRE2_EXP_DECL    for declarations
94   PCRE2_EXP_DEFN    for definitions
95 
96 The reason for wrapping this in #ifndef PCRE2_EXP_DECL is so that pcre2test,
97 which is an application, but needs to import this file in order to "peek" at
98 internals, can #include pcre2.h first to get an application's-eye view.
99 
100 In principle, people compiling for non-Windows, non-Unix-like (i.e. uncommon,
101 special-purpose environments) might want to stick other stuff in front of
102 exported symbols. That's why, in the non-Windows case, we set PCRE2_EXP_DEFN

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