Comment:
The last option on the gcc command line '-w' is there to suppress all
warnings. ('''A really really bad idea IMHO'''). If I remove that horrid
-w option, some more warnings are shown. Whether these aid in solving the
problem I do not know, but they do indicate a lot of potential problems
are being masked. This unfortunately is quite common in Sage, with
numerous bits of code using all sorts of tricks to hide warning messages.
