Ok, fine. Here is the *essential* patch.
The reason why I added variables was that with alignment iov's in the middle
one has to change the cnt - 2 to cnt - 3 etc., so I thought it would be
better to avoid changing all the following fields when some iov is inserted
in the middle.
Anyway, this patch fixes one more problems (&crncystr passed instead of
crncystr, causing the pointer to be written as the string) and
uses sizeof(uint32_t) instead of 4 for some word fields to make it obvious
it is not a 4 byte array but a word (requiring alignment).
I added some fields to categories.def which are missing there, but as I want
to leave that up to you, they are commented out at the moment.

2000-04-19  Jakub Jelinek  <jakub@redhat.com>

	* locale/programs/ld-ctype.c (ctype_output): Set size of the idx
	field to nelems * sizeof (uint32_t).
	* locale/programs/ld-address.c (address_output): Align word fields
	properly.
	* locale/programs/ld-monetary.c (monetary_output): Likewise.
	Don't restart idx pointers to idx end at the duo_int_curr_symbol
	field.
	Avoid giving arbitrary garbage in the crncystr field.
	Use sizeof(uint32_t) instead of 4 for len in uno_valid_from,
	uno_valid_to, duo_valid_from, duo_valid_to and conversion_rate
	fields.
	* locale/programs/ld-numeric.c (numeric_output): Likewise.
	Don't restart idx pointers to idx end at the decimal_point_wc field.
	* locale/programs/ld-time.c (time_output): week_1stday should be
	word, not byte.  Align it properly.
