Why? Around 1992-1997 I learned the lesson that one cannot really rely on the values of __STDC_VERSION__ and the like. Too many compilers lie about it.
Although that's certainly true in general, my guess is that this particular use of __STDC_VERSION__ would be OK. It has been used that way for something similar in Gnulib's lib/vla.h, without reported problems. Admittedly vla.h is a lot less used than gettext.h is (it's used only by GNU RCS as far as I know, and it assumes modern compilers).
It's a judgment call, and your patch is a reasonable one too.
