from gh.texi to data-rep.texi. Both files already had similar
descriptions for SCM. Given that gh.texi is deprecated, looking
up `SCM' in the index should take one to the primary location
rather than deprecated section. Hence this change. Added
`@deftp' for scm_t_bits data type so that a proper index entry is
added for this. Thanks to Richard Y. Kim!
* data-rep.texi (Subrs): Changed scm_make_gsubr to
scm_c_define_gsubr. Thanks to Richard Y. Kim!
