any plans for an "official" newlib snapshot ?

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
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
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
