Perfect.

Simplest is to put them in _SOURCES.  This is a convenience feature.
Next simplest is to list then in EXTRA_DIST.

Eric> hotwayd_LDADD = \
Eric>   libghttp-1.0.9-mod/ghttp.c \
Eric>   libghttp-1.0.9-mod/http_date.c \
Eric>   libghttp-1.0.9-mod/http_hdrs.c \
Eric>   libghttp-1.0.9-mod/http_req.c \
Eric>   libghttp-1.0.9-mod/http_resp.c \
Eric>   libghttp-1.0.9-mod/http_trans.c \
Eric>   libghttp-1.0.9-mod/http_uri.c \
Eric>   libghttp-1.0.9-mod/http_base64.c \
Eric>   libghttp-1.0.9-mod/http_digest.c \
Eric>   libghttp-1.0.9-mod/md5c.c

Don't do this!  This means all those files will be recompiled every
time the program is linked.

Yes, this would be better.

This approach should work ok.

Does libghttp have its own configure script?
If so it is probably even cleaner to run that.  Put this in
configure.in:

    AC_CONFIG_SUBDIRS(libghttp-1.0.9-mod)

Then put this in your Makefile.am:

    SUBDIRS = libghttp-1.0.9-mod

This is a better approach because it is more modular.  Your Makefile
won't need to know very much about the library at all.  This means
that upgrading the library probably won't introduce maintenance
problems for your code.

Why your approach failed, I don't know.  I assume you re-ran autoconf,
automake, and configure?
