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
