Re: [xml] Building libxml2 as a DLL under MinGW MSYS

That would break the current build with MS compiler. As things fare, that
dllexport while compiling libxml would produce a static library which
reexports all those symbols from the client program. GCC can automatically
export all nonstatic symbols, so I would suggest to either use that feature
or a .DEF file.

Neither Borland nor Microsoft #define __WIN32__, so that change would break
both compilers.

That file is autogenerated and modifying it brings nothing. Besides, perhaps
should the user be the one who decides if she needs iconv or not.

Unfortunately, these modifications break other platforms.

There is at least one more person who marches under the same banner. I
suggest you and Elisabeth cooperate in making MSYS/mingw work, it would be
the most productive way.
