problem with check for const in autoconf 2.13

[Luca Berra]

hello.
(i post here cause gnats does not work with lynx)
i found a configure script saying i have a non-working const,
i tracked the error down to autoheader.m4f, line 974
which reads
typedef int charset[2]; const charset x;

both egcs and gcc 2.95.2 reject this with:
"uninitialized const `x'", which seems a sensible thing to do for
a C++ compiler.

changing the line to read
typedef int charset[2]; const charset x = {0, 0};

works

regards.
Luca
