We investigate foundation models for detecting such errors and, in a controlled setting, restoring compilability in configurable C code. Study I evaluates GPT-OSS-20B on 5,000 synthetic snippets generated by ChatGPT-5.2 from 30 curated seeds and exhaustively compiled under all Boolean feature assignments; it also compares TypeChef and evaluates Gemini 3.6 Flash on a stratified sample. GPT-OSS-20B achieved 84.7% micro-precision and 52.1% micro-recall for affected configurations.
