Problems compiling a skin program

[Hans-Jürgen Ude]

I just wanted to try out the fusion skins (VxWorks interface) but get a
whole bunch of error messages when trying to compile one the simplest
programs.

------------- Top of file ------------
#include <vxworks/vxworks.h>
------------- Bottom of file ---------

the central errors are reported from
$FUSION/include/nucleus/intr.h:97: parse error before "xnintr_affinity"
$FUSION/include/nucleus/intr.h:97: parse error before
"xnintr_xnarch_cpumask_t"

Followed by hundreds of others, like an include file is missing. But i've
got no clue which one. Can someone give me a direction here? Fusion version
is 0.6.7. When trying Posix, similar or same things happen.

TIA,
Hans
