I do this, but can't reproduce the error.  Can you please be precise
about which file.h triggers the problem (send me a copy of it if it's
outside of Emacs, please) and what the "big modification" is.

I built the latest Emacs-24 last night.  I tried it with loading
.../emacs/src/lisp.h, then

M-5 M->
M-<
C-w
M-x revert-buffer<CR>yes

So, what file (?ffi.h) was it, please, and what did you do to it?

This error message has been thrown before in the medium past, but I
think this is something new.
