99 /* When compiling a DLL for Windows, the exported symbols have to be declared
100 using some MS magic. I found some useful information on this web page:
101 http://msdn2.microsoft.com/en-us/library/y4h7bcy6(VS.80).aspx. According to the
102 information there, using __declspec(dllexport) without "extern" we have a
103 definition; with "extern" we have a declaration. The settings here override the
104 setting in pcre.h (which is included below); it defines only PCRE_EXP_DECL,
105 which is all that is needed for applications (they just import the symbols). We
106 use:
107
108 PCRE_EXP_DECL for declarations
109 PCRE_EXP_DEFN for definitions of exported functions
110 PCRE_EXP_DATA_DEFN for definitions of exported variables
111
112 The reason for the two DEFN macros is that in non-Windows environments, one
113 does not want to have "extern" before variable definitions because it leads to
114 compiler warnings. So we distinguish between functions and variables. In
115 Windows, the two should always be the same.
116
117 The reason for wrapping this in #ifndef PCRE_EXP_DECL is so that pcretest,
118 which is an application, but needs to import this file in order to "peek" at
119 internals, can #include pcre.h first to get an application's-eye view.
120
121 In principle, people compiling for non-Windows, non-Unix-like (i.e. uncommon,
122 special-purpose environments) might want to stick other stuff in front of
123 exported symbols. That's why, in the non-Windows case, we set PCRE_EXP_DEFN and
124 PCRE_EXP_DATA_DEFN only if they are not already set. */

700 the characters so that they always use the ASCII/UTF-8 code when UTF-8 support
701 is enabled. When UTF-8 support is not enabled, the definitions use character
702 literals. Both character and string versions of each character are needed, and
703 there are some longer strings as well.
704
705 This means that, on EBCDIC platforms, the PCRE library can handle either
706 EBCDIC, or UTF-8, but not both. To support both in the same compiled library
707 would need different lookups depending on whether PCRE_UTF8 was set or not.
708 This would make it impossible to use characters in switch/case statements,
709 which would reduce performance. For a theoretical use (which nobody has asked
710 for) in a minority area (EBCDIC platforms), this is not sensible. Any

1287 definitions below, up to ESC_z. There's a dummy for OP_ALLANY because it
1288 corresponds to "." in DOTALL mode rather than an escape sequence. It is also
1289 used for [^] in JavaScript compatibility mode, and for \C in non-utf8 mode. In

1292 The special values ESC_DU, ESC_du, etc. are used instead of ESC_D, ESC_d, etc.
1293 when PCRE_UCP is set, when replacement of \d etc by \p sequences is required.

1297 The final escape must be ESC_REF as subsequent values are used for
1298 backreferences (\1, \2, \3, etc). There are two tests in the code for an escape
1299 greater than ESC_b and less than ESC_Z to detect the types that may be
1300 repeated. These are the types that consume characters. If any new escapes are
1301 put in between that don't consume a character, that code will have to change.
