Debian release of PCRE 4.5 had
 
 PCRE_LIB_VERSION=13:0:10
 PCRE_POSIXLIB_VERSION=13:0:10
 
 which corresponds to latest debian-revision (soname libpcre.so.3,
 installed as libpcre.so.3.9.0) and followed the instructions about version
 numbering in the libtool manual:
 |  3. If the library source code has changed at all since the last
 |     update, then increment REVISION (`C:R:A' becomes `C:r+1:A').
 
 13:1:10
 
   4. If any interfaces have been added, removed, or changed since the
      last update, increment CURRENT, and set REVISION to 0.
 
 14:0:10
 
   5. If any interfaces have been added since the last public release,
      then increment AGE.
 
 14:0:11
 
   6. If any interfaces have been removed since the last public release,
      then set AGE to 0.
 
 n/a
 
 Therefore I'm using 14:0:11 for this release of PCRE 5.0
