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

+This means that, on EBCDIC platforms, the PCRE library can handle either
+EBCDIC, or UTF-8, but not both. To support both in the same compiled library
+would need different lookups depending on whether PCRE_UTF8 was set or not.
+This would make it impossible to use characters in switch/case statements,
+which would reduce performance. For a theoretical use (which nobody has asked
+for) in a minority area (EBCDIC platforms), this is not sensible. Any
+application that did need both could compile two versions of the library, using
+macros to give the functions distinct names. */
+
+#ifndef SUPPORT_UTF
+
+/* UTF-8 support is not enabled; use the platform-dependent character literals
+so that PCRE works in both ASCII and EBCDIC environments, but only in non-UTF
+mode. Newline characters are problematic in EBCDIC. Though it has CR and LF
+characters, a common practice has been to use its NL (0x15) character as the
+line terminator in C-like processing environments. However, sometimes the LF
+(0x25) character is used instead, according to this Unicode document:
+
+http://unicode.org/standard/reports/tr13/tr13-5.html
+
+PCRE defaults EBCDIC NL to 0x15, but has a build-time option to select 0x25
+instead. Whichever is *not* chosen is defined as NEL.
+
+In both ASCII and EBCDIC environments, CHAR_NL and CHAR_LF are synonyms for the
+same code point. */

+then run on another where the size of pointers is different, all might still
+be well.
+
+The size of the structure must be a multiple of 8 bytes. For the case of
+compiled-on-4 and run-on-8, we include an extra pointer that is always NULL so
+that there are an even number of pointers which therefore are a multiple of 8
+bytes.
+
+It is necessary to fork the struct for the 32 bit library, since it needs to
+use pcre_uint32 for first_char and req_char. We can't put an ifdef inside the
+typedef because pcretest needs access to the struct of the 8-, 16- and 32-bit
+variants.
+
+*** WARNING ***
+When new fields are added to these structures, remember to adjust the code in
+pcre_byte_order.c that is concerned with swapping the byte order of the fields
+when a compiled regex is reloaded on a host with different endianness.
+*** WARNING ***
+There is also similar byte-flipping code in pcretest.c, which is used for
+testing the byte-flipping features. It must also be kept in step.
