These statements are labeled with a "WORKAROUND" comment; try just
deleting them.

If that doesn't work, see if there is something similar to set
Error_Msg_Name_* to.

Some news on GNAT-GPL-2007 on Mac OS X (powerbook):

The problem with No_Name is that it's defined in Namet, not Types.

A normal build ended up complaining that there was an inconsistency  
vs the system libraries (different exception handling model, I think).

I don't recognise the compiler options in gnatpath.gpr, so ended up  
using my standard ones (-g -O2 -gnatqQafoy) -- no change.

I rebuilt using gnatmake -a to recompile the RTS components needed:  
now fails to link with undefined symbol __gnat_link_max.

Turns out this is in link.c in gnat_src; compile that and build with  
gnatmake -Pgnatpath -a -largs link.o -- success!
