:Hi, I'm having any sort of troubles using /bin/cc under sr10.1 on

I reported the same problem to Apollo, and am trying to get them to
write an APR.  The SR10.0 cpp works fine, and intresting enough
the /bsd4.3/usr/lib/cpp works fine, but the /sys5.3/usr/lib/cpp
is broken.  What I did was to change the symbolic link
in /lib to a shell script that checks the environment.  If the
environment is Sys5.3, it call /bsd4.3/usr/lib/cpp -I/sys5.3/usr/include $*
else it calls /bsd4.3/usr/lib/cpp $*.  That work around seems to
be ok for now.
