I have an adainclude (and adalib) straight under 4.1.1. I don't see
any sign of a <runtime> subdir in the native RISC OS build, nor in the
working cross-compile build. And yes, "ads.system" (suffix swapped!)
is there under adainclude.

If I understand this stuff a bit, it's the zero-cost exception handling
which is used:
--8<--
recipe/files/gcc/ada/system-riscos-arm.ads: ZCX_By_Default :
constant Boolean := True;
recipe/files/gcc/ada/system-riscos-arm.ads: GCC_ZCX_Support :
constant Boolean := True;
recipe/files/gcc/ada/system-riscos-arm.ads: Front_End_ZCX_Support :
constant Boolean := False;
--8<--

But but but... you probably know then much more than I do !
Two questions:
1. I would like to get debug output where GNAT is looking for system.adb.
I think I want to set the debug option 'dl' (as mentioned in debug.adb)
but I simply fail to see how I can specify this on the command line.
Or won't dl help me ?
2. If I would upload the native RISC OS build, would you have time to have
a look to see what possibly is missing ? And/or to review the Ada
changes I made ?
John.
