I found these errors in the libwww source; no doubt not too many people
compile the code with the same options as I did ;-).  In brief:

    GETHOSTBYNAME_R should be replaced with HAVE_GETHOSTBYNAME_R,

    Compilation error.  Here is the required patch:

        diff -w -i -b -r2.2 HTSQL.c
        < 	struct * pgmt = gmtime_r(&t, &gmt);
        > 	struct tm *pgmt = gmtime_r(&t, &gmt);

* System files (e.g. <assert.h>) included _before_ wwwsys.h (and thereby
  bypassing the output of "configure"); these generate warnings on my

* Link Errors
    When configuring using --with-socks, the code would not link, due
    to some undefined references.  My system only has libsocks4
    installed.  Full details are found below.

* --enable-posix
    Why is it necessary (in configure.in, around line 990) to both
        (Why isn't the first approach sufficient?)

Now the boring details:

    My System: Debian/GNU Linux 2.4.4 i686 unknown
    Tools: "up-to-date" versions of gcc, automake, autoconf, libtool, etc.
    Configuration: this configuration did _not_ work:

    ./configure                  \
        --enable-reentrant       \
        --enable-signals         \
        --prefix=/usr            \
        --with-gnu-ld            \
        --with-mysql=mysqlclient \
        --with-regexp            \
        --with-socks             \
        --with-ssl               \

Relevant configure output:

    checking for getlogin_r... yes, and it returns an int
    checking whether to define _POSIX_SOURCE... no

* The compilation error, due to --enable-socks being passed to configure:
        Installed library is libsocks4 Version: 4.3.beta2-11.1

I did get the system to compile with this configure line:

    ./configure                  \
        --enable-nagle           \
        --enable-posix           \
        --enable-reentrant       \
        --enable-signals         \
        --prefix=/usr            \
        --with-gnu-ld            \
        --with-mysql=mysqlclient \
        --with-regexp            \
        --with-ssl               \

A final question: is Jose Kahan (or anyone else) still patching the
source, particularly with fixes to blatant bugs?
