-General Information
-~~~~~~~~~~~~~~~~~~~
-To compile this you need a couple things
-  - A working POSIX system with working POSIX gcc, g++, make (GNU),
-    ar, sh, awk and sed in the path
-  - GNU Make 3.74 or so, -- normal UNIX make will NOT work
-    * Note 3.77 is broken.    
-  - A working ANSI C++ compiler, this is not g++ 2.7.* 
-    g++ 2.8 works OK and newer egcs work well also. Nobody has tried it
-    on other compilers :< You will need a properly working STL as well.
-  - A C library with the usual POSIX functions and a BSD socket layer. 
-    If your OS conforms to the Single Unix Spec then you are fine:
-      http://www.opengroup.org/onlinepubs/7908799/index.html      
-  - Refer to the Build-Depends information in debian/control for
-    additional requirements (some of which are Debian-specific)
-
-** NOTICE **
-The C++ global constructors do not link correctly when using non-shared
-libraries. This is probably the correct behavior of the linker, but I have
-not yet had time to devise a work around for it. The correct thing to 
-do is add a reference to debSystem in apt-pkg/init.cc, 
-assert(&debSystem == 0) would be fine for instance.
-
-Guidelines
-~~~~~~~~~~
-I am not interested in making 'ultra portable code'. I will accept patches
-to make the code that already exists conform more to SUS or POSIX, but
-I don't really care if your not-SUS OS doesn't work. It is simply too
-much work to maintain patches for dysfunctional OSs. I highly suggest you
-contact your vendor and express interest in a conforming C library.
-
-That said, there are lots of finicky problems that must be dealt with even
-between the supported OS's. Primarily the path I choose to take is to put
-a shim header file in build/include that transparently adds the required 
-functionality. Patches to make autoconf detect these cases and generate the 
-required shims are OK.
-
-Current shims:
-  * sys/statvfs.h to convert from BSD/old-glibc statfs to SUS statvfs
-  * rfc2553 hostname resolution (methods/rfc*), shims to normal gethostbyname.
-    The more adventurous could steal the KAME IPv6 enabled resolvers for those
-    OS's with IPv6 support but no rfc2553 (why?)
-  * define _XOPEN_EXTENDED_SOURCE to bring in h_errno on HP-UX
-  * socklen_t shim in netdb.h if the OS does not have socklen_t
-  
-The only completely non-shimmed OS is Linux with glibc2.1, glibc2.0 requires
-the first three shims.
-
-Platform Notes
-~~~~~~~~~~~~~~
-Debian GNU Linux 2.1 'slink'
-Debian GNU Linux 'potato'
-Debian GNU Linux 'woody'
-  * All Archs
-  - Works flawlessly
-  - You will want to have docbook-xml and docbook2man installed to get
-    best results.
-  - No IPv6 Support in glibc's < 2.1.
-
-Sun Solaris
-  SunOS cab101 5.7 Generic_106541-04 sun4u sparc
-  SunOS csu201 5.8 Generic_108528-04 sun4u sparc  
-  - Works fine
-  - Note, no IPv6 Support, OS lacks RFC 2553 hostname resolution
-
-OpenBSD
-  OpenBSD gsb086 2.5 CMPUT#0 i386 unknown
-  OpenBSD csu101 2.7 CMPUT#1 i386 unknown  
-  - OS needs 'ranlib' to generate the symbol table after 'ar'.. (not using
-    GNU ar with the gnu tool chain :<)
-  - '2.5' does not have RFC 2553 hostname resolution, but '2.7' does
-  - Testing on '2.7' suggests the OS has a bug in its handling of 
-    ftruncate on files that have been written via mmap. It fills the page 
-    that crosses the truncation boundary with 0's. 
-    
-HP-UX
-  HP-UX nyquist B.10.20 C 9000/780 2016574337 32-user license
-  - Evil OS, does not conform very well to SUS
-     1) snprintf exists but is not prototyped, ignore spurious warnings
-     2) No socklen_t
-     3) Requires -D_XOPEN_SOURCE_EXTENDED for h_errno
-    configure should fix the last two (see above)
-  - Note, no IPv6 Support, OS lacks RFC 2553 hostname resolution
