Summary: 
Problems with EDE automake projects:
- necessary compiler detection is missing from generated configure.ac
- AUTHORS, NEWS, README, Changelog are regenerated on every build

Details for reproduction:
-  emacs -Q
-  M-x global-ede-mode RET
-  M-x semantic-mode RET
-  M-x make-directory RET /tmp/cedet-test1 RET
-  C-x C-f /tmp/cedet-test1/test.c RET
- [In the buffer:]
   #include <stdio.h>
   int main () { puts("Hello EDE!"); }
-  C-x C-s
-  M-x ede-new RET
  Project Type: Automake
  Name: edetest
-  C-c . t
  Name: hello
  Type: program
  Add test.c to hello? (y or n) y
-  C-c . c
  I had to create the AUTHORS file for you.  Ok? (y or n) y
  [Same question for NEWS, README, Changelog, all answerde `y']

Now I get compilation output:

  Compilation exited abnormally with code 1 at Wed Oct  7 11:19:30

As the error messages show: there is AC_PROG_CC or any equivalent
missing from the generated configure.ac.  After adding it manually:

- C-x b test.c RET
- C-c . c

Asks again for all files AUTHORS, NEWS, README and Changelog if they
should be created despite the fact that they are already there.  Even
more: it readds and thereby duplicates the automatic generated entries
(for AUTHORS and NEWS).

Answering no to any of there "create foo" questions immediately
terminates the whole ede build process, which IMO is a bug, too.

The actually build runs now successfully.
