+identifying release candidates. It might be defined as -RC2, for example. In
+real releases, it should be defined empty. Do not change the alignment of these
+statments. The code in ./configure greps out the version numbers by using "cut"
+to get values from column 29 onwards. These are substituted into pcre-config
+and libpcre.pc. The values are not put into configure.ac and substituted here
+(which would simplify this issue) because that makes life harder for those who
+cannot run ./configure. As it now stands, this file need not be edited in that
