Dear Maintainer,

At 3 places, the abs() function is used without being declared, resulting in
messages like the following one:

 src/bid64_pow.c: In function ‘__bid64_pow’:
 src/bid64_pow.c:183:17: warning: implicit declaration of function ‘abs’ [-Wimplicit-function-declaration]
   183 |       exact_y = abs(exact_y);

Fortunately, the compiler should infer the correct prototype in this case. It’s
however better to avoid such a situation (which is forbidden in C99 and C11,
though GCC does not enforce that rule by default).

I attach a patch.

Thanks for your work,
