The more evil thing is that currently *all* warnings in the

Unfortunately, this is all too common in many components of Sage. I find it very
worrying indeed.
'lcalc' had a particularly annoying attempt to cover up warnings from the
assembler, as it actually caused the build to break on Solaris, as the option to
cover up the warnings was passed directly to the Sun assembler, but it did not
accept the option.

IMHO, the quality of the coding in Sage leaves a lot to be desired in places.
