DJGPP supports stabs, so yes, I should be able to reproduce this.

Thanks, I will try that.

It requires async subprocesses that DJGPP doesn't support.  (And no, I 
cannot afford doing that in a cross-compilation environment, either.)

I wrote that because the number of changes that are retrofitted into the 
branch is disturbingly high (IMHO).  Perhaps Andrew should have held us 
under the threat of the branch slightly longer.

I alwaus thought that a branch is effectively feature-frozen.  Perhaps I 
misunderstood the policy.
