Hi,
I've decided I'm going to try to take the time and cleanup and update the Pascal frontend for gcc and try it get it integrated into the upstream source. I'm doing this because I wouldn't like to see GPC work with GCC 4+. I don't care at all at supporting GPC on anything less than GCC 4.1 so I've started by ripping out as much obviously compatibility code as I can and removing any traces of GPC being a separate project.
So far I have only accomplished converting lang-options.h to lang.opt. I'm going to continue cleaning up the GPC code, then once I am happy with how the code looks with respect to the rest of the GCC code, I'm going to get it to compile with the current version of GCC mainline. I'm starting with the boring conflict happy whitespace changes first so the code is easier for me to read and so that I can try to get an idea what the GPC frontend is doing.
My current changes are available through bazaar (an arch implementation) which people can get with: baz register-archive http://www.csclub.uwaterloo.ca/~ja2morri/arch baz get phython@gcc.gnu.org--pascal/gcc-pascal--mainline--0.3
Once I get the front-end to compile I'll look into creating a branch on gcc.gnu.org, but until that point it really isn't worth while. Patches are welcome, but please have your copyright assignment filed with the FSF and add a changelog entry to ChangeLog.gcc.
I don't have any timeline for this work.
