scandir not being included from dirent.h

Question

#include <stdio.h>
#include <stdlib.h>
#include <sys/stat.h>
#include <dirent.h>

int main(int argc, char const *argv[]){
    struct dirent **namelist;

    int n;
    n = scandir(".", &namelist, NULL, alphasort);

    printf("Number Files %d\n", n);

    if (n == -1){
        perror("scandir");
        exit(EXIT_FAILURE);
    }

    while (n--){
        printf("%s\n", namelist[n]->d_name);
        free(namelist[n]);
    }
}

I get an error for alphasort, "error: 'alphasort' undeclared (first use in this function)" and I get an implicit declaration of function 'scandir' error. Other programs successfully compile and include libraries.

I have made sure I have the dirent.h library on my computer. The VSCode quick fix is to edit include path settings but even when I add the path to C:\MinGW\x86_64-w64-mingw32\include which contains the library it does not compile.

MinGW doesn't appear to support scandir. It doesn't try provide POSIX APIs in general, the fact that opendir is provided is already a bit surprising.
