>Description:

makemandb always reports the same number for "Total Number of new or
updated pages enountered" and "Total number of (hard or symbolic)
links found". 

e.g.

Updating man page index:
Building temporary file cache
Total Number of new or updated pages enountered = 446
Total number of pages that were successfully indexed/updated = 0
Total number of (hard or symbolic) links found = 446
Total number of pages that could not be indexed due to errors = 0
Deleting stale index entries

>How-To-Repeat:

Run makemandb twice in quite succession. Note that the second time
it is run, it still reports new or updated man pages even though
no new man pages have been installed.

>Fix:
I haven't looked for a fix.
