aa41d2de | 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 | |
c86f6258 PH |
20 | things alone. */ |
