Yes, that turned out to be optimistic, for a few reasons.

Progress is stalled because the DejaGNU maintainer has not been seen on 
this list since March and I am unsure about working too far ahead of the 
"accepted" line.

There might be a merge conflict, but that will be easy to resolve by 
overwriting your patch with mine.  I will make sure to include the 
functionality in the rewrite.

I have just sent a patch to the list that has been waiting in my local 
repository since June.  It adds unit tests for the 
default_target_compile procedure, but currently verifies the broken Ada 
handling.  Would you be willing to supply a patch to update those tests 
to the correct behavior?  If so, I will also merge your code on my local 
branch and we might even avoid the merge conflict down the line.

While you are doing that, could you also explain what the various -?args 
GNU Ada driver options do and if any others are needed or could be 
needed?  I will ensure that the rewrite handles all cases if I can get a 
solid description of what those cases actually are.  The rewrite will 
group complier/linker/etc. options in separate lists internally, so 
using those options will be easy without adding more hacks to a 
procedure that has already become a tissue of hacks.
