error: identifier "S_ISUID" is undefined
I am attempting to port a benchmark from linux to windows. I am using the Intel C++ Compiler,
and I have C99 support enabled. When I try to build the project, I get the following errors:
.\decoder.c(192): error: identifier "S_ISUID" is undefined
      fchmod(fd, ~(S_ISUID | S_ISGID |S_IXGRP | S_IXUSR | S_IXOTH));
                   ^

.\decoder.c(192): error: identifier "S_ISGID" is undefined
      fchmod(fd, ~(S_ISUID | S_ISGID |S_IXGRP | S_IXUSR | S_IXOTH));
                             ^

.\decoder.c(192): error: identifier "S_IXGRP" is undefined
      fchmod(fd, ~(S_ISUID | S_ISGID |S_IXGRP | S_IXUSR | S_IXOTH));
                                      ^

.\decoder.c(192): error: identifier "S_IXUSR" is undefined
      fchmod(fd, ~(S_ISUID | S_ISGID |S_IXGRP | S_IXUSR | S_IXOTH));
                                                ^

.\decoder.c(192): error: identifier "S_IXOTH" is undefined
      fchmod(fd, ~(S_ISUID | S_ISGID |S_IXGRP | S_IXUSR | S_IXOTH));
                                                          ^

The portion of code that appears to be causing the errors is this:

Reassemble(void * args) {
  int chunkcount = 0;

  int fd = -1;
  struct chunk_list * list_head, * p;
  list_head = NULL;

  if (args != NULL) {
    fd = open((char *)args, O_CREAT|O_WRONLY|O_TRUNC);
    if (fd < 0) 
      perror("Reassemble open");
    fchmod(fd, ~(S_ISUID | S_ISGID |S_IXGRP | S_IXUSR | S_IXOTH)); //Error points to this line.
  }
  
  //The rest of the function...
  
}

fchmod() isn't C99; it's an IEEE 1003.1 "posix" function not found in a basic Windows installation.  SFU "services for linux" might support it in a compatible form.

You may need to change your code and use fileAccessControl() to implement this on Windows.
