EGCS-970929 and GNAT-3.10p?

[Jim Wilson]

	gnat-3.10p + testgcc-970803
	seems to work OK except for a configuration problem in which a variable in
	the generated ada/Makefile (target_alias) does not get substituted
	correctly.

This Makefile variable underwent a name change a few months ago, so this isn't
too surprising.  It should be easy to workaround.

	I did not investigate much but it seemed that the egcs reorganization
	compared to gcc 2.7.2.x may have broken something.  I need to try this all
	again to confirm it though.  

I don't believe that there is anything EGCS specific here.  It is just that
gnat-3.10p was released a few months ago, and does not include all of the
front-end/back-end interface changes that have been made since the gcc 2.7.2
release.  Many of these problems will likely be fixed by the gnat-3.11 release.
