GCC 2.95 does not look in /usr/local/include

I sent a patch many years for Linux to make gcc as the vendor compiler and
it was accepted. However, egcs didn't have the patch and I sent it again.
This time I was told egcs wouldn't be used as the vendor compiler and
someone might even remove my patch from the gcc subdirectory. That might be
ok since there was gcc 2.7.2.3. Now egcs == gcc. My patch should go in.

Here is the patch again.
