Thank you for your response. There is no information in the manual about make options, and a wget readme file which I found on the web is an extract from the manual. The makefile contains the make options, which is how I got to the construct in my original post.
Since you want to compile wget with the default options, you can simply set the BATCH env. variable to "yes" and run make. In bash, for example, you could do something like:
@ph0enix: not sure how to interpret your suggestion, there is no BATCH configuration option for wget. If I try your suggestion literally, I am receiving "command not found errors"
