I was wondering if there is anything could be done in the upcoming
gettext release. Let's go back to the original explanation by Bruno:
https://lists.gnu.org/archive/html/bug-gnu-utils/2006-03/msg00011.html
where he states two things:
1. The purpose of the checks are excluding incompatible implementations,
e.g., NetBSD (around 1.5?) and Solaris 7
2. The __GNU_GETTEXT_SUPPORTED_REVISION macro is a recent addition
In that case, I guess we could bypass the symbol checks if
__GNU_GETTEXT_SUPPORTED_REVISION is defined, as long as broken
implementations do not define it.
How about the attached patch?
