- The 'stripdecls.py' script replaces declarations in all headers by includes to generated headers. `ag '#\s*if(?!ndef NEOVIM_).*((?!#\s*endif).*\n)*#ifdef INCLUDE_GENERATED'` was used for this. - Add and integrate gendeclarations.lua into the build system to generate the required includes. - Add -Wno-unused-function - Made a bunch of old-style definitions ANSI This adds a requirement: all type and structure definitions must be present before INCLUDE_GENERATED_DECLARATIONS-protected include. Warning: mch_expandpath (path.h.generated.h) was moved manually. So far it is the only exception.
