I am trying to add variadic macro support for Boost and there is still a 
Digital Mars compiler config file there. From what I can see the config 
file supports versions 8.00 through 8.48, although I can easily change 
it to the latest version 8.52 as the latest. But without knowing which 
version and above, as reflected by the __DMC__ predefined macro, 
variadic macro support exists in Digital Mars C++, it is impossible to 
add it to the compiler config file so that end-users of Digital Mars C++ 
can use it in their code when using Boost libraries, or that Boost 
libraries themselves can incorporate variadic macros in their code, when 
a compiler suppors it, if they feel it would make their library easier 
to use.

Ok, I understand where you're coming from. But I'm pretty sure I did it a long 
time ago, like maybe 10 years ago.

In any case, upgrades to the latest DMC++ version are free for customers, so 
nobody should be stuck with an older version.

I just tried it with 8.12, dated 2001. Variadics work.

Are you suggesting that the earliest version supported in the Boost 
compiler configuration file for Digital Mars C++ be 8.12 rather than 
8.00 ? Because if it is kept as it is at 8.00, and despite the fact that 
customers can upgrade for free, I would need to know if variadic macros 
work or not with versions 8.00 through 8.11, or at the least I would 
need to be able to download such versions to try it for myself.

If it were my decision, I'd abandon support for DMC++ versions older than the 
current one, 8.52, because:

1. upgrades for DMC++ users are a free download

2. if they are upgrading Boost, why not update the compiler as well?

3. I don't support any versions other than the current one (by providing free 
upgrades to the current one)

Good. I will let the Boost developers know that they should abandon 
support of Digital Mars C++ for all but the latest version, at the 
suggestion of Walter Bright, who created the implementation.

Sounds good. Please send them the 3 reasons as well.

Reminds me of when back in the 80's, I was asked in a panel discussion if 
Zortech supported running the C++ compiler on a floppy disk only system. I said 
sure, it costs $200 extra and comes with a hard disk.
