    Log Message:
    Fix warnings raised by gcc -D_FORTIFY_SOURCE=3 -O1

    A bunch of possible (but often, not really) use of undefined values.
    Some ignored return values (e.g. of chsize/ftruncate, read, write, fgets).

    Other than some added diagnostics upon some of these unexpected syscall failures, there should be no change in behavior from this commit.
