The build ID now includes both last tagged version, commit generation
since last tagged version, as well as the leading characters of the
commit ID and a flag for dirty working tree.
(cherry picked from commit c2a0d3b969)
Autoconf and m4 copy the "#" comments from configure.in to configure.
This should make it easier to find the part of configure that was
expanded from a specific check in configure.in.
ELinks does not yet work with Lua 5.1 (see bug 742),
so the configure script should not suggest that it does.
When bug 742 is eventually fixed, ELinks should probably
prefer Lua 5.1 over 5.0, as the newer version seems likely
to be kept installed longer.

Actually, don't use the cfmakeraw function at all,
and don't look for it during configure either.
(cherry picked from commit 87f1661314
but moved the NEWS entry into the 0.12 section)
Because features.conf now contains CONFIG_UTF8=yes,
configure --enable-utf-8 is not useful, and it is better
to document configure --disable-utf-8.

This change:
- Adds a check for the doxygen program to configure.
- Moves the Doxyfile from src/Doxyfile to doc/Doxyfile.in.
- Generates a doc/Doxyfile from doc/Doxyfile.in inserting
an absolute path to the source directory, so that it
also works when builddir != srcdir.
- Adds `make api` rule for running doxygen; it depends on
api/doxygen file which is never created to force the rule
to always run.
Previously, an empty string as spidermonkeydir or luadir meant
that the LIBS and CFLAGS variables should be used unchanged. A few
commits ago however, the configure script was changed to require
test -f "$spidermonkeydir$spidermonkeyinclude/jsapi.h" and
test -f "$luadir/include/lua$suffix/lua.h" to succeed. These
commands interpret spidermonkeydir="" and luadir="" as the root
directory. This behaviour was inconsistent with the part that
decides whether to add the directory to *_LIBS and *_CFLAGS or not.
The inconsistency could be solved in two ways. Either (a) add an
exception so that the test -f is skipped if the variable is empty,
or (b) treat an empty string as the root directory throughout.
Because the Makefile of SpiderMonkey always installs to a subdirectory
of the specified include directory, and ELinks uses #include <jsapi.h>
without specifying that subdirectory in source code, it seems unlikely
that the SpiderMonkey header files would ever be in the default
include path. I am therefore implementing solution (b) here.
I suppose similar considerations apply to Lua but did not check that
carefully.
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.)
I'm not sure if JS_GetReservedSlot exists in all versions of the SpiderMonkey.
IMHO the configure script should check for JS_GetReservedSlot.
The patch in the attachment.
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.
The configure script checks whether it is possible to compile a use of
POPpx without an n_a variable; if not, the source code then defines
those variables. This is slower than including Perl's patchlevel.h
and comparing the version numbers to 5.8.8 but I expect this to be
more reliable as well.
