first_weekday for ca_ES is 2, but it has no first_weekday specified.
We would need some rationale for this change - please take a look at http://sourceware.org/glibc/wiki/Contribution%20checklist#Qualification_.28Locales.29 - thanks!
Hi, is this enough? http://ca.wikipedia.org/wiki/Dilluns "El dilluns és el primer dia de la setmana", which means "Monday is the first day of the week".
Oh, I'm sorry I bothered you - in fact, a change in this effect has already been committed two months ago! Fixed in commit c9e9d408631bf700fc975d315e4c6d8ce8d84d3c.
