Re: GNU Pascal is still kind of alive

Dear Chief,

I can hire a computer science student for the summer to work on GPC, but 
I don't think they will be capable of doing much with the migration to 
newer versions of GCC. They may be able to help with other projects.

I have no complaints.

Enhancing the compiler is something a CS student could attempt.

If we can be sure of compiling GCC 3.4.6 on Windows, Linux, and MacOS 
using whatever version of GCC is current for those platforms, then I 
think we should be okay. I'm confident we can do so on Windows 32-bit, 
Linux 32-bit and Linux 64-bit. I can't compile GCC 3.4.6 on Windows 
64-bit I believe because of divergeance between MinGW 64-bit and MinGW 
32-bit. On MacOS I can't compile GCC 3.4.6. It took me some time to get 
GPC to run on MacOS 10.7.5, but I just posted my notes on how to do that.

We (my group) is going to try to get the same MacOS GPC binaries working 
on MacOS 10.9 and later.

Okay. We will look into that here.

I have your os-hacks.h file. Is there more? If so, then yes I'm interested.

Yours, Kevan
