build failure, undefined symbols XML_...

[dk122 at torfree.net]

I am trying to build from the git tarball of 2012-11-03, commit id
445e66f, and the build fails in `[build LNK]
Library/libhelplinkerlo.so` because of undefined symbols referenced
from helpcompiler/source/HelpLinker.cxx:
     XML_ParserCreate_UTF8
     XML_Parse_UTF8
     XML_GetErrorCode_UTF8
     XML_ErrorString_UTF8
     XML_ParserFree_UTF8

workdir/unxlngi6/GenCObject/UnpackedTarball/expat/lib/xmlparse.o
appears to define these symbols, but I do not know how to get it into
the link command.


I shall try again when I can can get the next git tarball, but
meanwhile any advice is appreciated.


My build environment is ubuntu-natty 32-bit  ...

     $ uname -a
     Linux cougar-natty 2.6.38-16-generic #67-Ubuntu SMP Thu Sep 6  
18:00:43 UTC 2012 i686 athlon i386 GNU/Linux
     $ gcc --version
     gcc (Ubuntu/Linaro 4.5.2-8ubuntu4) 4.5.2

and the configuration options are

     --enable-symbols
     --enable-dbgutil
     --enable-crashdump
     --disable-build-mozilla
     --without-system-postgresql
     --enable-debug
     --enable-werror
     --without-myspell-dicts
     --without-help
     --with-system-expat


Thank you, all, for your attention,
Terry.
