+This code used to be here for use when compiling as a C++ library. However,
+according to Dair Grant it is not needed: "
+
+ Including 'extern "C"' in the declaration generates an "initialized and
+ declared `extern'" warning from gcc 4.0.1. Since we include pcre_internal.h,
+ which includes pcre.h, which declares these prototypes within an extern "C" {}
+ block, we shouldn't need the prefix here.
+
+So, from Release 7.0 I have cut this out.
