Modifying module help

Hi,

I’m doing a project on GPG security (yeah i know, original aren’t i?) As part of it i’m trying to build and run a version that lets me see when the random number generator is used.

I have downloaded the source and built an installer following the guide here:
http://www.gpg4win.org/build-installer-gnulinux.html

I want to modify the rndw32.c file and then rebuild the installer. Problem is that i can’t find it in the new source code (or using linux, i’m fairly new to it).

Any and all help welcomed, thanks.
