Hi.

Previously I reported a problem following.

To solve this problem, I made a patch for gcc-2.7.2.1.
This patch defines 'cacheflush' function for SONY NEWS-OS 4.2.

To test this patch, I compiled gstep-base-0.2.10(which uses
gcc's trampoline-feature intensively) and all examples
worked correctly.
