For example, neither Debian (and for that matter Ubuntu) nor Gentoo
guarantee that the en_US.UTF-8 locale is available.

We in particular encounter build problems on Gentoo when users have only
set very specific, non en_US locales, for example de_DE.UTF-8 (or
similar).

We face the same problem in Gentoo and usually advice users to set
LC_ALL=3DC when submitting bug reports. (It is frustrating that glibc
upstream doesn't get their act together fixing and merging the current
C.UTF-8 proposal.)

So what about making the build system more robust (by merging the
patches, or a variant) and either setting C.UTF-8, or C globally
(depending on availability)?

Best,
