[PATCH] Increment value instead of a pointer in ADA macro processing.

[Martin Liška]

Hello.

Looks there's real issues spotted by -Wchkp:

../../gcc/c-family/c-ada-spec.c: In function ‘void 
print_ada_macros.chkp(pretty_printer*, 
\xe2\x80\x98pointer_bounds_typ\xe2\x80\x99 not supported by dump_type#<type 
error>, cpp_hashnode**, \xe2\x80\x98pointer_bounds_typ\xe2\x80\x99 not 
supported by dump_type#<type error>, int, void, ...)’:

I prepared quite obvious fix for that and tested make check -k 
RUNTESTFLAGS="dg.exp=dump-ada-spec-*"
on x86_64-linux-gnu.

Ready to be installed?
