That's a bug in hhc.exe which always returns a non-zero error code.
That's documented in the help/Makefile, as I recall.

Double-click on the foo.chm installed and check it works is the only test.
But in hundreds of tests I have never seen hhc complete and produce an
invalid .chm.

I always run make pkgcheck-foo after Rcmd INSTALL foo, which checks all
the examples.

Or since you must run this from a terminal (commands prompt or whatever)
you can have a small batch file which sets the path as needed for building
R packages.  That's what I do, as otherwise the path can get too long.
>From what I read Windows NT variants accept paths of more than 262 chars,
but only parse the first 262 characters (which explains a problem Marc
Feldesman had with HHW a long time ago).
