  • updated to PCRE 6.1

The original PCRE 6.1 sources are checked into the tree with the tag
"pcre-6-1" for reference. What we're checking in right now is the original
plus our changes to make it support UTF-16 and at least one other tweak
(vertical tab considered whitespace). Our work to get our changes was
done on "pcre-6-1-branch", with an anchor at "pcre-6-1-anchor" so you can
see the evolution of the UTF-16 changes.

Note also that there was one small change made here that's not on the branch
in pcre_compile.c.

  • Info.plist: Updated the part of the copyright message that's about PCRE.
  • JavaScriptCore.xcodeproj/project.pbxproj: Added new PCRE source files, removed obsolete ones.
  • pcre/AUTHORS: Updated to PCRE 6.1. Includes credits for Apple's UTF-16 changes, but not the credits for Google's C++ wrapper, since we don't include that.

     1/* On Unix systems config.in is converted by configure into config.h. PCRE is
     2written in Standard C, but there are a few non-standard things it can cope
     3with, allowing it to run on SunOS4 and other "close to standard" systems.
     4
     5On a non-Unix system you should just copy this file into config.h, and set up
     6the macros the way you need them. You should normally change the definitions of
     7HAVE_STRERROR and HAVE_MEMMOVE to 1. Unfortunately, because of the way autoconf
     8works, these cannot be made the defaults. If your system has bcopy() and not
     9memmove(), change the definition of HAVE_BCOPY instead of HAVE_MEMMOVE. If your
     10system has neither bcopy() nor memmove(), leave them both as 0; an emulation
     11function will be used. */

     36normally be defined with the value 1 for other systems, but unfortunately we
     37can't make this the default because "configure" files generated by autoconf
