The attached patch modifies csc to use temporary files (as created
by "create-temporary-file") for intermediate .c and .o files. This
is actually trickier than it sounds. The tests succeed so far,
but there may be corner cases that are not covered yet.
This fixes #946, which was reported by Alan Post.
cheers,
felix
