>Environment:
Minix 3.2.1 (which uses makewhatis.c, v 1.47 2009/04/02 21:39:33 apb from 
NetBSD)
>Description:
makewhatis in the above version of Minix does not create an entry in whatisdb 
for some man pages. Therefore even though these man pages exist, they will not 
appear if you use apropos to search for them. It seems that GNU man pages 
"generated by Pod" are the main culprits. The following changes to makewhatis.c 
fixed the problem for me:

>How-To-Repeat:
Run makewhatis with GNU man pages "generated by Pod" (e.g. clang.1) - an entry 
will NOT be generated in the whatisdb.

diff result:
