Hello Shevek,

thanks for the report.

Actually, we're reluctant to change the test, because it's quite likely
that those old compilers barfed over the code only without the
initializations.

The general recommendation is to either avoid using -Werror, or to just
drop AC_C_CONST: unless you know of a system with a compiler that
doesn't support const, chances are you won't ever meet one.  These are
all just museum systems, and maybe a couple of long-running servers
(which is why AC_C_CONST hasn't been eliminated yet IIRC).

Cheers,
Ralf
