| 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. |
| 10 | |
| 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. */ |
