[Coin-discuss] problems with cross-compiling CoinUtils for Windows

[Laszlo Ladanyi]

I seem to remember that the __MSVCRT__ was taken off because that caused 
problems with some combination of cygwin/msys/gcc/cl, but I may be wrong. If 
someone has access to these, could you test that Kish's change does not break 
things?

Thanks,
