I'm in the middle updating my system but this seems to work ok for me..

It is difficult to pin down as the error comes from cpp, which is run by
pcc, which is run by nbmkdep, which is run by nbgenassym .. can you run
the command again but add an "-v" option directly after the "assym.dep"
part? That should show what mkdep is doing, and if that seems ok, you can
also add "-v" into the pcc options (just before "-msoft-float") which will
tell pcc to output the commands it runs
