++## Preprocessing of Source Files
++
++Certain files in the build require preprocessing to filter in/out
++parts which differ between vanilla JS builds and ES6 Module
++(a.k.a. esm) builds. The preprocessor itself is in
++[](/file/ext/wasm/c-pp.c) and the associates flags and rules are in
++[](/file/ext/wasm/GNUmakefile).
