[Tinyos-devel] TCAST definition

[John Regehr]

Roman-

TCAST is a new macro used by Safe TinyOS, it means "trusted cast".

Please do a "make install" in $TOSROOT/tools.  This will upgrade you to 
the latest version of ncc, which knows how to deal with TCAST.

If you care, it is dealt with by including

   $TOSDIR/lib/safe/include/annots_stage1.h

If you haven't built the TinyOS tools before, you'll want to run 
./Bootstrap and ./configure (with an appropriate --prefix option) before 
installing the tools.  Please let me know if this fails to fix the problem 
you are seeing.
