when I import all the GA Library files and "Build" it, it shows (In VC++
2005 Express Edition)....
Creating library...

ga - 0 error(s), 7 warning(s)
Ignoring the warnings when I import an example from the 'examples' given
with "galib246", then it's showing many errors.I'm sending those errors for
the example(ex9.cpp) I used.
