Indeed, it does.

However, the scoping of the define symbols in this file seems somewhat
confused.

For example:

>   static void
>   KillExistingArchiveStatus(void)
>   {
>   #define ARCHSTATDIR XLOGDIR "/archive_status"

This define was presumably intended to be used only within the function,
but since it is a macro, it can also be used from other functions, which
appears to have contributed to this mistake.

It would be better to clearly distinguish between file-scoped symbols
and function-scoped ones. For function-local constants like this,
using a 'static const char[] instead of a macro would make the
intended scope explicit and help prevent similar issues.

regards.
