I believe hark sng-'s problem had to do with having GNAT installed, which
"hijacks" every other installation via a registry entry. See my "fixes"
area for workaround:
http://www.xraylith.wisc.edu/~khan/software/gnu-win32/gcc.html#gcc295-fixes

My next release of gcc will *ignore* these hidden registry entries to avoid 
these conflicts. Hopefully GNAT folks will take care and use a more 
reasonable key next time (vendor specific versioned key perhaps) to avoid
this problem.

You need to be sure of that if that is indeed the case (that it worked
for a short period)!

If you don't have GNAT installed, then we obviously need to figure this
out. Please look through the output of:
  
  $ gcc -print-search-dirs

and see where it's looking for things.

  $ gcc -print-file-name=specs

should print the full pathname to the specs files.

Thanks. These look good.

Not the "builtin specs". That means GCC is just not finding what it's
supposed to.

Earnie, the newer versions of gcc provide two different cpp's -- one
goes in <exec_prefix>/bin and other one goes deep into the compiler
directory. GCC uses *only* the second one, and the first one is provided
for other programs or users who may want to run cpp directly (eg., imake).
