    Fix warnings raised by gcc -D_FORTIFY_SOURCE=3 -O1 · 8667e329
    Rob Swindell authored
    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.
