Correct.

The same thing happens for an out of tree build.

I agree.

Not that I can see.  The program source windows/doc2html.c
contains the comment 
/*
 * doc2html.c  -- program to convert Gnuplot .DOC format to MS Windows
 * HTML help (.html) format.

So I think it is only needed for windows. By the way, when I run the program
it only processes Part I of the documentation.  Parts 2-5 are ignored.
So the program may have bugs separate from this build problem.
