I'm pretty sure you broke _CloseArchive with this hunk:

@@ -708,6 +708,9 @@ _CloseArchive(ArchiveHandle *AH)
{
WriteHead(AH);
tpos = ftello(AH->FH);
+ if (tpos < 0 || errno)
+ exit_horribly(modulename, "could not determine seek position in archive file: %s\n",
+ strerror(errno));
WriteToc(AH);
ctx->dataStart = _getFilePos(AH, ctx);

There's no reason to assume errno is zero at entry, and in any case
it should not be necessary to test for anything except tpos < 0.

I'm not sure why _ReopenArchive is coded like it was; seems like
tpos < 0 should be a sufficient test there too, and we shouldn't have to
reset errno beforehand.
