Right, although it was trivially fixable.
Also, having duplicated ajd almost identical code is also a good source
of bugs, so I disagree with the above.

Also easily fixable.

I disagree, it reduces the potential for bugs and discrepencies.

I also disagree, I find the use of GNU Make very handful.
I just believe you (and other GCC folks) are not yet ready to use these
features, that's all :-)

Having used GNU Make for GNAT for years now (compare to a very recent
switch in that direction for the rest of GCC), I find it very valuable,
and find overuse of configure not necessarily preferrable, in particular
since configure is by itself a big hack which is painful to maintain :-)

Anyway, I don't have any particular problem with your proposed patch.
What I really didn't like in your previous change was the overuse of 'sh'
embedded in Makefile, which *is* very error-prone and painful to maintain.
