Hi Karl,

if I remember correctly we did discuss not to install, e.g., dh.h some time
ago, but cnf.h is more recent and I did not mention it.  More below.

Hi all,

it was done on purpose, but doing so was a mistake, now reverted (r26437).

I had seen that (in the TeX Live tree) kpathsea_cnf_get() and
<kpathsea/cnf.h> are used only inside the library, but missed that they are
advertized in the texinfo manual.

Evince should #include <kpathsea/cnf.h> if and only if they use
kpathsea_cnf_get() [or kpse_cnf_get()].
