121 ph10 145 /* 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 ph10 154 information there, using __declspec(dllexport) without "extern" we have a
125 ph10 145 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 ph10 154 which is all that is needed for applications (they just import the symbols). We
128     use:
129 ph10 145
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 ph10 154 internals, can #include pcre.h first to get an application's-eye view.
142 ph10 145
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. */

2303     use pcre_uint32 for first_char and req_char. We can't put an ifdef inside the
2304     typedef because pcretest needs access to the struct of the 8-, 16- and 32-bit
2305 ph10 1320 variants.

2307 ph10 1320 *** WARNING ***
2308     When new fields are added to these structures, remember to adjust the code in
2309 ph10 1313 pcre_byte_order.c that is concerned with swapping the byte order of the fields
2310     when a compiled regex is reloaded on a host with different endianness.
2311     *** WARNING ***
2312 ph10 1320 There is also similar byte-flipping code in pcretest.c, which is used for
2313 ph10 1313 testing the byte-flipping features. It must also be kept in step.
