This patch implements a `long double' suggestion by Oliver Kiddle.

* lib/autoconf/c.m4 (AC_LANG_BOOL_COMPILE_TRY(C)): Make the array
static, to catch errors if the value isn't known at compile-time
and the compiler supports dynamic arrays.  Change its name from
`_array_' to `test_array' to avoid potential name clashes.
(AC_C_LONG_DOUBLE): Make it a compile-time test, not a run-time
test.  Do not define HAVE_LONG_DOUBLE if `long double' is no
better than double.  Catch a bug in GCC 2.95.2 x86.
* doc/autoconf.texi (C Compiler): Document the above.
* NEWS: Likewise.
