[Trilinos-Users] linking debug on Windows

[Bartlett, Roscoe A]

Matthew,

I don't think that "free" is a resolved keyword in C++ so any implementation that creates a macro called 'free' is a non-ANSI compliant C++ implementation as far as I can tell.

Being that is the case, if there is no work around then we might be able to change the name of the free(...) member function to destroy(...) or something but that technically will break backward compatibility.

Cheers,

- Ross
