Hello Brett,
Thank you very much for analyzing the cintdll problems.
This kind of problem is quite popular with STL. Every C++
compiler has different STL implementation. Even worst, they
change implementation from version to version. And so far,
I have not seen any compiler which is fully compliant to ANSI/ISO
C++. Some look very close, but down to this detail, there is
difference.
I'll try RH7.2 soon. If it comes with gcc3.1/3.2, I can work on it.
Thank you
Masaharu Goto
