Yah forward declaration is not needed, and it worked without it this time.
I don't know why it was showing "int count_no_of_records( DBM *db_local )
not found".

Did that.
This formatting rule is not mentioned in
https://devel.rtems.org/wiki/Developer/Coding/Conventions
in case of loops, should i add it?

And this one too, it is no where mentioned about wrapping up functions calls
in 80 characters, when needed, in this site
https://devel.rtems.org/wiki/Developer/Coding/80_characters_per_line
Should I add this too?

Yah, actually it was due to my coding style, I usually use pointer
arithmetic when using pointers, and hence mentioned comment.
Although I have replaced it with test_strings[5] = '\0', now.
