How to patch for: #include <bits/wordsize.h>

[Mayuresh <mayuresh%acm.org@localhost>]

On NetBSD 10.1 amd64, I am trying to build a project that includes above
header.

Precise usage of this header is in the following form in the code:

    #if __WORD_SIZE==32

The header is present on Linux systems but not on NetBSD. On NetBSD, how
should this be patched? Even better if the patch is generic and works on
Linux as well.
