Taking this to the jamboost list, where it's more appropriate...

It is hard to follow sometimes ;-)

First, for different compilers the only way to set that is through the TOOLS
variable. Seeing as other people will have different tools there's now way,
and no desire, to speficy that in the Jamfiles. But you could set an
environment var in your system to always be set, as enviroment vars are
automatically imported into bjam.

Second, the release+debug variants. You can specify those in the Jamfile, as
the sixth argument to the "run" rule. Interesting is that that's the only
testing rule you can specify that ony. But I would not suggest you do this.
The regression testing would probably (not really sure) not work if
something in addition to 1 variant got built. And this is, again, something
you really want to set in the command line. But you can set it globally in
the BUILD env variable if you don't like typing ;-)

That leaves, 30 tests/5 compile defines. For that I would suggest writting a
rule which runs through the list of 5 defines and generates the tests. For
example: (rough code hastily typed into email...)

rule apply-run ( sources + : args * : input-files * : requirements * : name
local tests ;
local defines = DEF1 DEF2 DEF3 DEF4 DEF5 ;
for local def in $(defines)
tests += [ run $(sources) : $(args) : $(input-files)
: $(requirements) <define>$(def) ] ;

And use that instead of the regular "run" testing rule.

PS. If you post your Jamfile, I'm sure we can be more informative ;-)
