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

1201 the characters so that they always use the ASCII/UTF-8 code when UTF-8 support
1202 is enabled. When UTF-8 support is not enabled, the definitions use character
1203 literals. Both character and string versions of each character are needed, and
1204 there are some longer strings as well.
1205
1206 This means that, on EBCDIC platforms, the PCRE library can handle either
1207 EBCDIC, or UTF-8, but not both. To support both in the same compiled library
1208 would need different lookups depending on whether PCRE_UTF8 was set or not.
1209 This would make it impossible to use characters in switch/case statements,
1210 which would reduce performance. For a theoretical use (which nobody has asked
1211 for) in a minority area (EBCDIC platforms), this is not sensible. Any
