This locale stuff is all still very confusing and highly non-portable.
On Sun, the man pages of strerror and perror mention

although I couldn't manage to actually get any effect on strerror with 
setlocale.
On Linux, strerror does depend on the environment variable LANG, so it's 
not a constant mapping function as some applications might desire, 
especially if they add their own, non-localized, text output. I don't 
know if there is a library function corresponding to this dependency, 
I had thought it would have to be setlocale.
