The following is what I use to emulate 4.2 directory stuff in non-4.2
systems. It has worked fine so far, touch wood. I suppose you could
improve it by making readdir an extern, but since I generally use this
for patching 4.2-type sources that's overkill. If you wanted to spend
time pleying with setjmp/longjmp you could even make it a macro!
You'll still have to patch any references to weirder parts of struct direct,
oh well.

#ifndef BSD
#define opendir(n) fopen(n, "r")
#define DIR FILE
static DIR *readdir(dp)
DIR *dp;
{
static struct direct db[1];
while(fread(db, sizeof(struct direct), 1, dp)) {
if(db->d_ino)
return db;
}
return NULL;
}
#define closedir fclose
#endif
