Weak points:
- alignof
- js problems
Todo:
- make js work with C++ and mozjs-17
- then mozjs-24
- then mozjs-52
- then mozjs-60
- decrease number of warnings
This legacy header appears to be unused. Removing its includes
avoids numerous warnings when compiling with musl libc:
/usr/include/sys/signal.h:1:2: warning: #warning redirecting incorrect #include <sys/signal.h> to <signal.h> [-Wcpp]
There was hardcoded 4096 for threads size, but below there was:
assertm(fd >= 0 && fd < FD_SETSIZE,
"get_handler: handle %d >= FD_SETSIZE %d",
fd, FD_SETSIZE);
if_assert_failed return NULL;
which fails for fd > 1024 (1024 was previous value of FD_SETSIZE)
INIT_OPTION used to initialize union option_value at compile time by
casting the default value to LIST_OF(struct option) *, which is the
type of the first member. On sparc64 and other big-endian systems
where sizeof(int) < sizeof(struct list_head *), this tended to leave
option->value.number as zero, thus messing up OPT_INT and OPT_BOOL
at least. OPT_LONG however tended to work right.
This would be easy to fix with C99 designated initializers,
but doc/hacking.txt says ELinks must be kept C89 compatible.
Another solution would be to make register_options() read the
value from option->value.tree (the first member), cast it back
to the right type, and write it to the appropriate member;
but that would still require somewhat dubious conversions
between integers, data pointers, and function pointers.
So here's a rather more invasive solution. Add struct option_init,
which is somewhat similar to struct option but has non-overlapping
members for different types of values, to ensure nothing is lost
in compile-time conversions. Move unsigned char *path from struct
option_info to struct option_init, and replace struct option_info
with a union that contains struct option_init and struct option.
Now, this union can be initialized with no portability problems,
and register_options() then moves the values from struct option_init
to their final places in struct option.
In my x86 ELinks build with plenty of options configured in, this
change bloated the text section by 340 bytes but compressed the data
section by 2784 bytes, presumably because union option_info is a
pointer smaller than struct option_info was.

Conflicts:
src/protocol/fsp/fsp.c: All options had been removed in 0.13.GIT.
src/protocol/smb/smb2.c: Ditto.
The GNU Hurd has a bug that can make select() report an exception in a
pipe even though none has actually occurred. The typical result is
that ELinks closes the pipe through which it internally passes all
input events, such as keypresses. It then no longer reacts to what
the user is trying to do.
Work around the Hurd bug by making set_handlers() check whether the
file descriptor refers to a pipe, and if so, pretend the caller did
not provide any handler for exceptions. This is a minimal change that
avoids slowing down the select() loop itself and does not require
careful analysis of the callers to statically find out which file
descriptors might refer to pipes. The extra stat() calls may slow
ELinks down somewhat, but anyway it'll work better than it did without
the patch, and if the Hurd bug is ever fixed, we can remove the
workaround at that time.

The following files also conflicted, but they had not been manually
edited in the elinks-0.12 branch after the previous merge, so I just
kept the 0.13.GIT versions:
doc/man/man1/elinks.1.in
doc/man/man5/elinks.conf.5
doc/man/man5/elinkskeys.5
po/fr.po
po/pl.po
This reverts commit c33d195ff4.
ELinks no longer needs to collect garbage in this situation
because it can now free cache entries even if the corresponding
SMJS objects remain.
Wrap on spaces when features are sent to console using -version,
and let Info dialog do the job in interactive mode.
Insert newlines and remove parenthesis in -version and Info box display.
Backported from master branch.
There were conflicts in src/document/css/ because 0.12.GIT switched
to LIST_OF(struct css_selector) and 0.13.GIT switched to struct
css_selector_set. Resolved by using LIST_OF(struct css_selector)
inside struct css_selector_set.
string_concat reads the args with va_arg(ap, const unsigned char *),
and the NULL macro may have the wrong type (e.g. int).
Many places pass string literals of type char * to string_concat.
This is in principle also a violation, but I'm ignoring it for now
because if it becomes a problem with some C implementation, then so
will the use of unsigned char * with printf "%s", which is so
widespread in ELinks that I'm not going to try fixing it now.
The configure script no longer recognizes "CONFIG_UTF_8=yes" lines
in custom features.conf files. They will have to be changed to
"CONFIG_UTF8=yes". This incompatibility was deemed acceptable
because no released version of ELinks supports CONFIG_UTF_8.
The --enable-utf-8 option was not renamed.
