Bad declaration of function g() in configure script (due to C23 strictness)

The configure script was run with no command line options, and it failed
the "long long reliability test 1":
configure: error: could not find a working compiler, see config.log for
details

The problem is in the function declarations in lines 6571 and 8190 of the
configure script

Instead of:
void g(){}

These lines need to be changed to:
void g(int, const t1 *, int, t1 *, const t1 *, int){}

(Presumably this is the C23 standard's strictness regarding empty
parameter lists, now meaning 0 arguments whereas 6 were expected)

After this modification, the configure script ran successfully to
completion, and "make" and "make check" also succeeded.
