There should be a Restriction pragma setting that can warn about code
that requires a runtime. There doesn't seem to be one in LRM 13.12. Ah;
there are a bunch more in Annex D.

Apparently the only list of restrictions in GNAT is in the source code
(not a manual); lib/gcc/i686-pc-mingw32/4.5.4/adainclude/s-rident.ads

The following seem likely to help:

No_Implicit_Heap_Allocations
No_Secondary_Stack
No_Tasking
