Will cause segmentation fault on anything that isn't 32bit about c2ada HOT 5 OPEN

Hi @apfeltee I am thrilled you are interested in c2ada and I am ok with you doing as you see fit with the version you have created. I have not had time to work more on c2ada so it is great you are maintaining and revising this code. Please feel free to advertise the project at a new location and to take the lead on it--I purposely licensed the code as MIT so anyone can do what they want with it. Also, I would be pleased to merge fixes and enhancements back into my fork, too. I have no problem with you also calling the new revision "c2ada"--I can always tag the version I currently have--I could rename my version "c2ada_classic" to make it distinct from the one you are on. I did not initially realise you had also separately imported from Source Forge. May I also please suggest considering the addition of a licence to your version so others can freely use it.

I do not claim exclusive ownership of the code, especially as it originated from other people--I just felt strongly that it should be shared on GitHub and licensed under a permissive licensing scheme, so I imported it from Source Forge and gave it the MIT licence. So please feel free to take the lead on it, enjoy, and keep in touch--I think it is great you are working on c2ada--many thanks and I look forward to seeing where it goes.

I'm glad you're ok with the changes, @mikequentel. As for the license, it's already implied that the original license still applies, though I'll add a note in the readme, as well as a license file.

Right now I'm mostly doing it out of curiosity, not so much out of need for a ada->c compiler, but it's always fun to take a second glance at older stuff ;-)

Also, on a perhaps unrelated note: The generated file uses imports from files, such as "c-ops.ads", etc. But I'm not sure where I'm supposed to get those, tbh. That's the main issue that keeps me from properly testing c2ada. :-(
Full listing from gnat make:

hello.adb:1:06: file "c.ads" not found
hello.adb:2:06: file "c-ops.ads" not found
hello.adb:3:06: file "stdarg.ads" not found
hello.adb:4:06: file "c-pointers.ads" not found

Hi @apfeltee I do not know about those files but maybe Nasser Abbasi would know--he was the maintainer of the code in Source Forge.

You can find the missing stdarg.ads here: http://www.cs.uofs.edu/~beidler/Ada/win32/stdarg.ads as it seems to provide the expected interfaces.

The rest is more tricky. c.ads, c-pointers.ads don't exist as such. The generated code should use Interfaces.C, Interfaces.C.Strings and Interfaces.C.Pointers (see http://www.adapower.com/rm95/RM-B-3-2.html). That would solve a big part of the issues, but not all, because the code expects some constructs from these package that don't exist (anymore?), like a type named charp. In Interfaces.C.Strings you find instead a type named chars_ptr, which seems to correspond. Once this is fixed, there are further namespace issues.

To conclude, it seems that the code generator requires quite a huge refresh to produce code that works with a recent GNAT compiler.

(Sorry for the belated response from my side)

@maxime-esa Awesome! That puts the whole thing back on track. Tracking those namespace issues down seemed easy at first, but it needs some more digging. I haven't considered that the standard had changed that much... but it gives me a reason to read up some more on Ada 😄

If it would turn out to be really necessary, then I'm sure I could re-implement these missing structures as prelude code, or somesuch.
