This can be reproduced with
$ cat test.c
# define _GL_ADD_OVERFLOW(a, b, min, max)
__builtin_add_overflow (a, b, (__typeof__ ((a) + (b)) *) 0)
$ gcc -c test.c
test.c:2:34: error: expected ‘)’ before ‘(’ token
__builtin_add_overflow (a, b, (__typeof__ ((a) + (b)) *) 0)

This is a problem in gnulib, introduced by

intprops.h: use __typeof__ with GCC 7
* lib/intprops.h (_GL_ADD_OVERFLOW, _GL_SUBTRACT_OVERFLOW)
(_GL_MULTIPLY_OVERFLOW): Use __typeof__ as in the GCC manual.
This avoids computing the expression's value (which might overflow!).

"Only a promise," Lao Er said.
