Update to 6.3. Take maintainership.

Version 6.3 15-Aug-05
---------------------

 1. The file libpcre.pc.in did not have general read permission in the tarball.

 2. There were some problems when building without C++ support:

    (a) If C++ support was not built, "make install" and "make \ 
test" still
        tried to test it.

    (b) There were problems when the value of CXX was explicitly set. Some
        changes have been made to try to fix these, and ...

    (c) --disable-cpp can now be used to explicitly disable C++ support.

    (d) The use of @CPP_OBJ@ directly caused a blank line preceded by a
        backslash in a target when C++ was disabled. This confuses some
        versions of "make", apparently. Using an intermediate variable \ 
solves
        this. (Same for CPP_LOBJ.)

 3. $(LINK_FOR_BUILD) now includes $(CFLAGS_FOR_BUILD) and $(LINK)
    (non-Windows) now includes $(CFLAGS) because these flags are sometimes
    necessary on certain architectures.

 4. Added a setting of -export-symbols-regex to the link command to remove
    those symbols that are exported in the C sense, but actually are local
    within the library, and not documented. Their names all begin with
    "_pcre_". This is not a perfect job, because (a) we have to except some
    symbols that pcretest ("illegally") uses, and (b) the facility \ 
isn't always
    available (and never for static libraries). I have made a note to try to
    find a way round (a) in the future.
