This was an attempt to extend the C programming language with advanced error handling constructs, similar to those seen in Rust today. It's a compiler taking a C-like dialect and compiles to pure C.

While trying to build I'm getting this errors:

And after this dirty changes I've got it to build but fail the tests:

Also I've just added the grammar/lexer to https://mingodad.github.io/parsertl-playground/playground/ an Yacc/Lex compatible online (wasm) editor/tester (select C2c-err-transpiler parser from Examples the click Parse to see a parse tree for the content in Input Source).

The above post (https://github.com/petergtz/c2c-err-transpiler/issues/1#issuecomment-2363065361) seems to be a scam reported here https://ianspence.com/blog/2024-09/github-email-hijack/ , please delete it.
