After doing a binary search, the first revision which breaks bootstrap on
my environment with Ada enabled is the following:

* Makefile.in (tree-ssa-ccp.o): Add $(PARAMS_H) to rule.
* tree-ssa-ccp.c (params.h): Include.
(fold_builtin_alloca_for_var): New function.
(ccp_fold_stmt): Use fold_builtin_alloca_for_var.
Which makes sense, since Ada uses alloca a lot, much more than other languages.
In other words, none of the changes in the Ada repository is reponsible for
this regression.
So Tom and/or Richard, could you please have a look at this regression? TIA.
