RE: RE : VC++6.0 and 7.0 are not supported anymore from ROOT4-04-2 or newer

Hi,

in principle there is no "fundamental" problem with VC 6.0. However, compilers get closer to the ansi standard. For example std::atof & co. do no longer pose a problem to VC 7.1 nor to gcc 3.2 and above.
For windows the OS version should not play a big role (win2k, winXP and probably still NT4) work nicely with VC 6 and VC 7.1.

Besides the differences to the ansi standard VC 6 however has known problems. One is e.g. the uselessness of std::map because they cannot be passed through dlls due to the lousy implementation. Also other STL stuff is different from the implementations coming with gcc or VC 7.1.

After myself having fought VC 6 for year I can only encourage the move to VC 7.1.
>From my experience the move is traight forward and the
platform independence due to differences in the C++ compiler with linux is nearly for free.
