[Bf-committers] Re: MEM_CacheLimiter breaks msvc6 compile unrepairable

[Stealth Apprentice]

MSVC8 is a no-cost download for the full environment,
unlike the MSVC7 downloads, 8 includes the
optimizer... MSVC6 has numerous template
implementation bugs. As things like elbeem get
introduced into the codebase, MSVC6 is going to become
more & more of a liability.
