Hi Robert,
I think yours is probably the right answer. My mibindex file is NOT well formed
but it does contain a line feed
DIR /mibs<LF>
But the fact that it doesn't get filled with all the mib files raises a flag
anyway. My toolchain doesn't have the dirent.h header and I'm using a custom
implementation coded by another person in my company. There is probably a bug
(or non-compliance) there somewhere.
Thank you all very much for your clarifications

Then it sounds like your mibindex file is not well formed. It should start with
a DIR line, followed by a line for each mib. e.g.
--- start ---
DIR /usr/share/snmp/mibs
AGENTX-MIB AGENTX-MIB.txt
--- end ---
The first line is read by fgets():
fgets() reads in at most one less than size characters from stream and
stores them into the buffer pointed to by s. Reading stops after an
EOF or a newline. If a newline is read, it is stored into the buffer.
So the strlen - 1 chops off the newline.

Static buffers/arrays should be initialized before use. If you find any that
are used before they are initialized, please file a bug and, if you can, submit
a patch to fix them.
