The `limits.h` header file in C provides the necessary information

Create a simple C program that includes the `limits.h` header and
prints the value of `LONG_BIT`.
#include <stdio.h>
#include <limits.h>
int main() {
printf("LONG_BIT: %d\n", LONG_BIT);
return 0;
}
This will output the number of bits in a "long" integer on your system.
Or use AC_COMPUTE_INT. You can do something like
AC_COMPUTE_INT([var], [LONG_BIT], [#include <limits.h>])
