OK, so you propose to store 0 in the 32-bit size field of the trailer
if the file is too large. The gzip folk, on the other hand, seem to
have decided to let gzip continue to store (size & 0xffffffff) in the
32-bit size field, and to make gunzip verify that (size & 0xffffffff) is
correct. (See the patch in http://www.gzip.org/4g-patch.tar.) I expect
that the difference will lead to interoperability problems.
