Example warning (5.0 compiled in and loaded):

[notice] ModSecurity: PCRE compiled version="5.00"; loaded version="5.0
13-Sep-2004"
[warn] ModSecurity: Loaded PCRE do not match with compiled!

pcre_version() is implemented as
  XSTRING(PCRE_MAJOR.PCRE_MINOR PCRE_DATE)

I propose to use in ModSecurity:

    pcre_vrs = apr_psprintf(mp,"%d.%d ", PCRE_MAJOR, PCRE_MINOR);

(note the space, which prevents that "8.2 " and "8.20" are considered
equal).
