When setting the tty device to raw mode, save the VERASE character.
Later, compare incoming bytes to that.
This is somewhat complicated because "stty verase undef"
sets termios.c_cc[VERASE] = _POSIX_VDISABLE, and e.g. Linux
defines _POSIX_VDISABLE as 0 but that must not cause ELinks
to treat incoming null bytes as backspaces. Furthermore,
some systems may use different VDISABLE values for different
terminal devices, in which case _POSIX_VDISABLE is undefined
and ELinks must instead read the value from fpathconf().
It is unlikely because the standard members of struct sockaddr_in
(sin_family, sin_port, sin_addr) already require at least 8 bytes
and I don't know of any system that has size_t larger than that.
Besides, at least glibc pads the structure to 16 bytes.
When get_pasv6_socket was merged into get_pasv_socket on 2005-04-15,
the AF_INET6 of get_pasv6_socket was lost and the merged function
always returned AF_INET sockets. This then made getsockname fill
only part of the struct sockaddr_in6, and ELinks sent to the server
an EPRT command that had half the bits missing from the IPv6 address.
At least ftp.funet.fi then rejected the command, helpfully saying
what the address should have been.
This commit fixes active FTP over IPv6. Passive FTP was already fixed
in 0.11.3.GIT (887d650efe), on 2007-05-01.
On machines where sizeof(size_t) > sizeof(int), this could corrupt the stack.
I think -Wno-pointer-sign added by configure hid this bug until now.
STRLEN is correct in Perl 5.6.0 and later, perhaps earlier too.
Bug 972 was fixed in this commit, and reported afterwards:

I'm not fully updating NEWS yet. Just this one bug.
The SpiderMonkey support in ELinks now uses JS_GetReservedSlot,
which was added in SpiderMonkey 1.5 RC3a, released on 2001-05-11.
So ELinks no longer supports earlier versions of SpiderMonkey.
However, be careful not to claim that ELinks needs "SpiderMonkey
1.5 RC3a or later", because we haven't tested 1.5 RC3a.
(I guess we didn't test zlib 1.2.0.2 either... oh, well.)
The history converted from CVS is not in repo.or.cz though, so keep
referring to pasky.or.cz for that. (We don't seem to use
"gitweb.elinks.cz", which is a DNS alias for pasky.or.cz.)
<paakku> Do you think we should maybe point people to gitweb at
repo.or.cz rather than pasky.or.cz?
<pasky> absolutely
<pasky> actually I thought we already are pointing people at
repo.or.cz
<pasky> at least there was some movement to do that already, I believe
:)
It was reported at elinks-dev on 2007-06-03 that Solaris 10 comes with
zlib 1.1.4, which does not include gzclearerr(), which ELinks nowadays
requires. It would be possible to rewrite the decompression support
to use deflate() directly and avoid stdio, in which case gzclearerr()
would not be needed. That will take some time however, so I'm not
attempting it for ELinks 0.12.0. Instead, I'm just disabling gzip
decompression entirely if zlib is too old.
