As of PCRE 8.33, config.h.generic no longer contains boolean macros. Two
of them (SUPPORT_PCRE8 and HAVE_MEMMOVE) were added to appropriate makefiles.
This allows PCRE 8.33 to compile and don't change anything for previous
versions.
On Mac OS X system toolchain by default prefers include files
from /usr/local/include, but libraries from /usr/lib. This might result in
various problems, in particular the one outlined below.
If the PCRE library is installed into /usr/local/, this results in pcre.h
being used from /usr/local/include (with PCRE_CONFIG_JIT defined), but
libpcre from /usr/lib (as shipped with the OS, without pcre_free_study()
symbol). As a result build fails as we use pcre_free_study() function
if we try to compile with PCRE JIT support.
Obvious workaround is to the root cause is to ask compiler to prefer
library from /usr/local/lib via ./configure --with-ld-opt="-L/usr/local/lib".
On the other hand, in any case it would be good to check if the function
we are going to use is available, hence the change.

options as --with-zlib=../zlib-1.2.3. It seems there is no common way
to learn the current directory in Win32 make's: although nmake has MAKEDIR
variable, nevertheless Borland make's MAKEDIR is the directory where make
is installed, and OpenWatcom wmake has no MAKEDIR at all.
*) Feature: the "server_names" directive supports the ".domain.tld"
names.
*) Feature: the "server_names" directive uses the hash for the
"*.domain.tld" names and more effective hash for usual names.
*) Change: the "server_names_hash_max_size" and
"server_names_hash_bucket_size" directives.
*) Change: the "server_names_hash" and "server_names_hash_threshold"
directives were canceled.
*) Feature: the "valid_referers" directive uses the hash site names.
*) Change: now the "valid_referers" directive checks the site names
only without the URI part.
*) Bugfix: some ".domain.tld" names incorrectly processed by the
ngx_http_map_module.
*) Bugfix: segmentation fault was occurred if configuration file did
not exist; the bug had appeared in 0.3.12.
*) Bugfix: on 64-bit platforms segmentation fault may occurred on
start; the bug had appeared in 0.3.16.
*) Change: the "valid_referers" directive and the "$invalid_referer"
variable were moved to the new ngx_http_referer_module from the
ngx_http_rewrite_module.
*) Change: the "$apache_bytes_sent" variable name was changed to
"$body_bytes_sent".
*) Feature: the "$sent_http_..." variables.
*) Feature: the "if" directive supports the "=" and "!=" operations.
*) Feature: the "proxy_pass" directive supports the HTTPS protocol.
*) Feature: the "proxy_set_body" directive.
*) Feature: the "post_action" directive.
*) Feature: the ngx_http_empty_gif_module.
*) Feature: the "worker_cpu_affinity" directive for Linux.
*) Bugfix: the "rewrite" directive did not unescape URI part in
redirect, now it is unescaped except the %00-%25 and %7F-%FF
characters.
*) Bugfix: nginx could not be built by the icc 9.0 compiler.
*) Bugfix: if the SSI was enabled for zero size static file, then the
chunked response was encoded incorrectly.
*) Feature: the Sun Studio 10 C compiler support.
*) Feature: the "proxy_upstream_max_fails",
"proxy_upstream_fail_timeout", "fastcgi_upstream_max_fails", and
"fastcgi_upstream_fail_timeout" directives.
*) Change: if the request header has duplicate the "Host",
"Connection", "Content-Length", or "Authorization" lines, then nginx
now returns the 400 error.

parameters of the "listen" directive.
*) Feature: the FreeBSD accept filters support.

in UTF-8.
*) Bugfix: the new log file can be rotated by the -USR1 signal only if
the reconfiguration by the -HUP signal was made twice.
*) Change: the invalid client header lines are now ignored and logged
at the info level.
*) Change: the server name is also logged in error log.
*) Feature: the ngx_http_auth_basic_module module and the auth_basic
and auth_basic_user_file directives.
*) Bugfix: the ngx_http_stub_status_module showed incorrect statistics
if "rtsig" method was used or if several worker process ran on SMP.
*) Bugfix: nginx could not be built by the icc compiler on Linux or if
the zlib-1.2.x library was building from sources.
*) Bugfix: nginx could not be built on NetBSD 2.0.
*) Bugfix: the proxied request was sent without arguments if the
request contains "//", "/./", "/../" or "%XX".
*) Bugfix: the large compressed responses may be transferred not
completely.
*) Bugfix: the files bigger than 2G was not transferred on Linux that
does not support sendfile64().
*) Bugfix: while the build configuration on Linux the
--with-poll_module parameter was required; the bug had appeared in
0.1.8.
*) Bugfix: in the ngx_http_autoindex_module if the long file names were
in the listing.
*) Feature: the "^~" modifier in the location directive.
*) Feature: the proxy_max_temp_file_size directive.
*) Bugfix: on Solaris and Linux there may be too many "recvmsg()
returned not enough data" alerts.
*) Bugfix: there were the "writev() failed (22: Invalid argument)"
errors on Solaris in proxy mode without sendfile. On other platforms
that do not support sendfile at all the process got caught in an
endless loop.
*) Bugfix: segmentation fault on Solaris in proxy mode and using
sendfile.
*) Bugfix: segmentation fault on Solaris.
*) Bugfix: on-line upgrade did not work on Linux.
