Don't know; C89 didn't say anything at all about them, so existing C
practice is all over the map; C99 does say something about them, but whether
a C99 compiler supports them is optional (support for them isn't mandatory;
if a C implementation does choose to support them, then the spellings for
input are standardized, although a locale is allowed to *produce* any
spellings whatsoever).
