There is an error when complie with glibc-2.34: comparison of integer expressions of different signedness: 'size_t' {aka 'long unsigned int'} and 'long int' [-Werror=sign-compare] The reason is that PTHREAD_STACK_MIN may be defined long int which is signed in glibc-2.34+. Explicitly assign it to the size_t variable to fix it.
