I have now tried to create a pure object-code module from C, so I
followed the approach above but left out the scm_ensure_user_module
part.  The definitions made via gh_new_procedure et al. don't seem to
get exported reliably.  In fact, when I initialize a sequence of
modules like this, only the first one's bindings seem to get
exported.  When using the other modules, Guile reports "No code for
module...", and in fact, the bindings are all missing.

Am I missing something?
