+/* This file contains character tables that are used when no external tables
+are passed to PCRE by the application that calls it. The tables are used only
+for characters whose code values are less than 256.
+
+This is a default version of the tables that assumes ASCII encoding. A program
+called dftables (which is distributed with PCRE) can be used to build
+alternative versions of this file. This is necessary if you are running in an
+EBCDIC environment, or if you want to default to a different encoding, for
+example ISO-8859-1. When dftables is run, it creates these tables in the
+current locale. If PCRE is configured with --enable-rebuild-chartables, this
+happens automatically.
+
+The following #includes are present because without the gcc 4.x may remove the
+array definition from the final binary if PCRE is built into a static library
+and dead code stripping is activated. This leads to link errors. Pulling in the
+header ensures that the array gets flagged as "someone outside this compilation
+unit might reference this" and so it will always be supplied to the linker. */

+****************************************************************************
+ RECURSION IN THE match() FUNCTION
+
+The match() function is highly recursive, though not every recursive call
+increases the recursive depth. Nevertheless, some regular expressions can cause
+it to recurse to a great depth. I was writing for Unix, so I just let it call
+itself recursively. This uses the stack for saving everything that has to be
+saved for a recursive call. On Unix, the stack can be large, and this works
+fine.
+
+It turns out that on some non-Unix-like systems there are problems with
+programs that use a lot of stack. (This despite the fact that every last chip
+has oodles of memory these days, and techniques for extending the stack have
+been known for decades.) So....
+
+There is a fudge, triggered by defining NO_RECURSE, which avoids recursive
+calls by keeping local variables that need to be preserved in blocks of memory
+obtained from malloc() instead instead of on the stack. Macros are used to
+achieve this so that the actual code doesn't look very different to what it
+always used to.
+
+The original heap-recursive code used longjmp(). However, it seems that this
+can be very slow on some operating systems. Following a suggestion from Stan
+Switzer, the use of longjmp() has been abolished, at the cost of having to
+provide a unique number for each call to RMATCH. There is no way of generating
+a sequence of numbers at compile time in C. I have given them names, to make
+them stand out more clearly.
+
+Crude tests on x86 Linux show a small speedup of around 5-8%. However, on
+FreeBSD, avoiding longjmp() more than halves the time taken to run the standard
+tests. Furthermore, not using longjmp() means that local dynamic variables
+don't have indeterminate values; this has meant that the frame size can be
+reduced because the result can be "passed back" by straight setting of the
+variable instead of being passed in the frame.

+information there, using __declspec(dllexport) without "extern" we have a

+ PCRE_EXP_DECL for declarations

+ 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
