Perfect ;-)

Great, so let's start then. There's one major compatibility problem I
haven't fixed yet:
 - libc/include/sys/unistd.h defines MAXNAMLEN as 1024
 - on Linux, d_name in struct dirent is 256 bytes long

Right now, I define the right MAXNAMLEN in libc/sys/linux/sys/dirent.h,
so depending on what you include first, you get the correct value or
not. (libc/sys/sparc64/sys/dirent.h seems to fight with similar issues.
sun4 and decstation just have a plain #define. Not sure how well they
compile ...)

The easiest solution would be remove the #define from
libc/include/sys/unistd.h and to add the following to libc/include/dirent.h

#if !defined(MAXNAMLEN) && !defined(_POSIX_SOURCE)
#define MAXNAMLEN 1024
#endif

after including sys/dirent.h. That way, sys/dirent.h can reliably
provide the correct value.

But I'm not sure if this is compatible with wherever that MAXNAMLEN
appeared originally. (BTW, glibc 2.1.3 also defines it in dirent.h, not
unistd.h)

Comments ?
