Great job. Thanks for doing this !

I have had the following issues/questions while trying to go through the
compilation using your tarball of compiled libraries (as comments (Mo:)
within your compile instructions (Pa:)):

Pa: Download and run the MinGW installer. Let it download and install what
it needs.

Mo:

- I imagine I have to tell the installer to install g++ and mingw make ?
- I imagine you just forgot to mention the install of msys ?


Pa: Also install: flex from gnuwin32.sourceforge.net and put flex.exe in
Mingw bin directory

Mo: Why not flex from mingw ? And all I need to do is copy flex.exe,
nothing else ?

Pa: Use bison from Mingw as Gnuwin32 bison looks for libintl3.dll

Mo: I did that, but I get this error:

cannot open file `/msys/share/bison/m4sugar/m4sugar.m4': No such file or
directory
make[3]: *** [y.tab.h] Error 1

It is in /mingw/share/bison/m4sugar/m4sugar.m4. I don't know why it is
looking for it in msys ? This causes an error in the compilation of
libvect and so many consequent errors.

Mo: What about the shared files from proj, such as epsg (in share
directory when ./configure&&make&&make install of proj in msys), they are
not in your tarball

Mo: during compilation, I get many errors concerning unfindable
libz.dll.1.2.3; apparently program tries to launch db.*  grass exe files
such as db.columns, etc during compilation. Don't know why.
After copying all files from c:\forgrass\lib to
c:\grasssrc\grass6\dist*\lib no more error messages during compilation.
You mention copying these after compilation. What am I doing wrong ?
