pastebins suck a bit because somebody reading this thread some months
down the road will not be able to see it.  Anyway.

You can simply add the generated file to nodist_libeet_la_SOURCES
instead of to libeet_la_SOURCES.

If I were you, I'd replace the first half of the generated file
eet_amalgamation.c with an
  #include "header-for-the-big-source-file.h"

and then I'd try to get my other headers to be idempotent so that you
can replace the rest with a loop
  for f in $(libeet_la_SOURCES); do \
    case $$f in \
      *.c) echo '#include "$$f"' >> $@;; \
    esac; \
  done

and if you don't need to cater to lots of different compiler versions,
then I'd just use a compiler/linker that can do whole-program/link-time
optimization (like GCC 4.5 will, and some others also do), and forget
about this hack.

Cheers,
Ralf
