Interesting. I've been testing my -Wc++-compat patches with full
bootstraps including Ada, but I just looked at my make log and it does
indeed appear that -Wc++-compat doesn't make it onto the Ada files.
It seems to be because of this line in ada/gcc-interface/Make-lang.in:

Next issue is that gnat1 link fails on many missing symbols:

I don't really know how the Ada compiler works, but it looks like this
code is generated by the gnatbind program. I bet it would work if
gnatbind -C emitted this at the start of the output:
#ifdef __cplusplus
extern C {
#endif
and emitted this at the end:
#ifdef __cplusplus
