115  #ifndef PCRE_SPY  /* When compiling a DLL for Windows, the exported symbols have to be declared
116  #define PCRE_DEFINITION       /* Win32 __declspec(export) trigger for .dll */  using some MS magic. I found some useful information on this web page:
117    http://msdn2.microsoft.com/en-us/library/y4h7bcy6(VS.80).aspx. According to the
118    information there, using __declspec(dllexport) without "extern" we have a
119    definition; with "extern" we have a declaration. The settings here override the
120    setting in pcre.h (which is included below); it defines only PCRE_EXP_DECL,
121    which is all that is needed for applications (they just import the symbols). We
122    use:
123    
124      PCRE_EXP_DECL       for declarations
125      PCRE_EXP_DEFN       for definitions of exported functions
126      PCRE_EXP_DATA_DEFN  for definitions of exported variables
127    
128    The reason for the two DEFN macros is that in non-Windows environments, one
129    does not want to have "extern" before variable definitions because it leads to
130    compiler warnings. So we distinguish between functions and variables. In
131    Windows, the two should always be the same.
132    
133    The reason for wrapping this in #ifndef PCRE_EXP_DECL is so that pcretest,
134    which is an application, but needs to import this file in order to "peek" at
135    internals, can #include pcre.h first to get an application's-eye view.
136    
137    In principle, people compiling for non-Windows, non-Unix-like (i.e. uncommon,
138    special-purpose environments) might want to stick other stuff in front of
139    exported symbols. That's why, in the non-Windows case, we set PCRE_EXP_DEFN and
140    PCRE_EXP_DATA_DEFN only if they are not already set. */

1204    the characters so that they always use the ASCII/UTF-8 code when UTF-8 support
1205    is enabled. When UTF-8 support is not enabled, the definitions use character
1206    literals. Both character and string versions of each character are needed, and
1207    there are some longer strings as well.
1208    
1209    This means that, on EBCDIC platforms, the PCRE library can handle either
1210    EBCDIC, or UTF-8, but not both. To support both in the same compiled library
1211    would need different lookups depending on whether PCRE_UTF8 was set or not.
1212    This would make it impossible to use characters in switch/case statements,
1213    which would reduce performance. For a theoretical use (which nobody has asked
1214    for) in a minority area (EBCDIC platforms), this is not sensible. Any
1215    application that did need both could compile two versions of the library, using
1216    macros to give the functions distinct names. */

1221    so that PCRE works in both ASCII and EBCDIC environments, but only in non-UTF
1222    mode. Newline characters are problematic in EBCDIC. Though it has CR and LF
1223    characters, a common practice has been to use its NL (0x15) character as the
1224    line terminator in C-like processing environments. However, sometimes the LF
1225    (0x25) character is used instead, according to this Unicode document:
1226    
1227    http://unicode.org/standard/reports/tr13/tr13-5.html

1229    PCRE defaults EBCDIC NL to 0x15, but has a build-time option to select 0x25
1230    instead. Whichever is *not* chosen is defined as NEL.
1231
