[ECOS] error of gcc3.4.4

[吴身国]

Hi,
  I had compiled GCC3.4.4 as my active compiler. under the eCos default gcc3.2.1, I can compile the ecos kernel and redboot.
  But use the same template, it can't be compiled, the output windows display:

We don't current support 3.4.4 by default.

You need to edit you ecos.ecc file and remove the
-mno-short-load-words from CYGBLD_GLOBAL_CFLAGS

It might work then.
