The glibc FAQ still has this in it:

2.17.   I have /usr/include/net and /usr/include/scsi as symlinks
        into my Linux source tree.  Is that wrong?

{PB} This was necessary for libc5, but is not correct when using glibc.
Including the kernel header files directly in user programs usually does not
work (see question 3.5).  glibc provides its own <net/*> and <scsi/*> header
files to replace them, and you may have to remove any symlink that you have
in place before you install glibc.  However, /usr/include/asm and
/usr/include/linux should remain as they were.


It's the version that's in cvs, I just did an cvs update.  It's
been in it for ages.  If it's wrong, someone *please* correct it.
