Dear Frank,
I use GPC for all my compiled code, and have no plans to stop using it. I far prefer Pascal to C. I will do whatever I can to keep GPC alive. I am a big fan of the schema types of GPC, as compared to the implementation in Borland or FPC.
I'm not an expert at C programming, so if the compiler is written in C, I'm not going to be much good with it. But if the compiler is written in Pascal, and compiles itself, I will be very happy to start trying to host the development of GPC myself, using some sort of version control code like GIT. I usually work on MacOS, so I could cover the interface with the MacOS operating system. We would need other people to work on the interface with the other operating systems.
I could dedicate 2 hours a week to maintenance of GPC, plus I have static IP addresses for hosting the code. At the very least, I could maintain the existing versions.
Yours, Kevan
