    Hi,

    at http://www.leidinger.net/FreeBSD/current-patches/ I have some patches
    which allow to compile the kernel with icc (CC=icc make depend && CC=icc
    make). They are a joint effort of Marius Strobl and me.

    The resulting kernel still has some issues (no NFS, some packet loss,
    ... see icc.README in the above mentioned directory), but it boots and
    runs.

    A quick tour over icc.diff:
     - build infrastructure: just a "translate gcc switches into icc
       switches"-game
     - includes: more or less "if gcc" -> "if gcc or intel compiler"
     - assym.h: icc doesn't handle 0 sized arrays like gcc does, the
       patch was suggested by bde, a discussion of this is in the
       archive
     - aicasm: understand the icc syntax of -nostdinc
     - stdargh.h and _types.h: the changes are just a reminder to
       enable them when icc understands this particular gcc syntax,
       Intel is working on it

    I run parts of these patches since a long time (months, parts of it over
    a year), no bad interactions with a gcc compiled kernel/world so far.

    Bye,
    Alexander.
