It would be nice if dmd -showversions output all the version constants 
defined by the compiler.  Why do I say this?  Because it's much more 
convenient than searching through the digital mars web site for predefined 
constants, then trying to figure out if those constants are defined or not 
by trying to compile a file with those version constants in it.  And this 
should be done in both D 1.0 and 2.0, as it doesn't affect the language.

BTW, if there is already some way to do this, please let me know :)

you still need to find the things to check but this will give you a yes no:

mixin(DefinedP!("ver123"));

template DefinedP(char[] ver)
{
   const char[] DefinedP = 
"version("~ver~"){pragma(msg,`+"~ver~"`)}else{pragma(msg,`-"~ver~"`)}";
}

I proposed this and more about a year ago:

 And this should be done in both D 1.0 and 2.0, as it doesn't affect the 
 language.


You mean DMD 1.x and 2.x I presume.
