Geoffrey, consider this a bug report, which is why I'm also directly
cc'ing you. 

On Windows 95, if an executable calling fork() lives in a
network-mounted directory, the fork() fails with errno = 13 (EACCES -
Permission denied).

Here's a simple example. If you put this executable on a network-mounted
drive, it will fail. If it is on a local drive, it will succeed:

    #include <errno.h>
 
    main(int argc, char **argv)
    {
        int pid;
 
        printf("In %d\n", getpid());
        if (argc == 1) {
            if ((pid = fork()) == 0) {
                /* child */
                execl(argv[0], argv[0], "dummy", 0);
                printf("execl of %s failed\n", argv[0]);
            } else if (pid == -1) {
                printf("fork failed - errno = %d\n", errno);
            } else {
                int *x;
                printf("In parent of %d\n", pid);
                wait(&x);
            }
        }
    }

Is there any workaround for this at all? I've been unable to find any
(even specifying the full path fails).

Thanks,
