   7 /* The PCRE sources include config.h, which for a free-standing PCRE build gets
   8 set up by autoconf. For the embedded version in Exim, this file, which is
   9 manually maintained, is used.

  11 The only configuration thing that matters for the PCRE library itself is
  12 whether the memmove() function exists or not. It should be present in all
  13 Standard C libraries, but is missing in SunOS4. PCRE expects autoconf to set
  14 HAVE_MEMMOVE to 1 in config.h when memmove() is present. If that is not set, it
  15 defines memmove() as a macro for bcopy().
  16
  17 Exim works differently. It handles this case by defining memmove() as a macro
  18 in its os.h-SunOS4 file. We interface this to PCRE by including the os.h file
  19 here, and then defining HAVE_MEMOVE so that PCRE's code in internal.h leaves
  20 things alone. */
