Thanks. It looks like you haven't changed 'is_base_and_derived.c'. Is that just a mistake, or is there a reason?
It's because I missed it :-( Fixed now.
Try bjam -sTOOLS=dmc -sDMC_ROOT=C:\dm
That still doesn't work for me, I'm afraid. The Digital Mars standard library is very dated, so you have to use stlport, but the header directories seem to get listed in the wrong order. I'll look into more and take it up on the boost build list sometime.
Same for me, I see (correct error messages this time!): ...found 46 targets... ...updating 13 targets...
