121    /* When compiling a DLL for Windows, the exported symbols have to be declared
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. */

1212    character constants like '*' because the compiler would emit their EBCDIC code,
1213    which is different from their ASCII/UTF-8 code. Instead we define macros for
1214    the characters so that they always use the ASCII/UTF-8 code when UTF-8 support
1215    is enabled. When UTF-8 support is not enabled, the definitions use character
1216    literals. Both character and string versions of each character are needed, and
1217    there are some longer strings as well.
1218    
1219    This means that, on EBCDIC platforms, the PCRE library can handle either
1220    EBCDIC, or UTF-8, but not both. To support both in the same compiled library
1221    would need different lookups depending on whether PCRE_UTF8 was set or not.
1222    This would make it impossible to use characters in switch/case statements,
1223    which would reduce performance. For a theoretical use (which nobody has asked
1224    for) in a minority area (EBCDIC platforms), this is not sensible. Any
1225    application that did need both could compile two versions of the library, using
1226    macros to give the functions distinct names. */

1233    characters, a common practice has been to use its NL (0x15) character as the

1235    (0x25) character is used instead, according to this Unicode document:
