Quick intro to "patch" (Was Re: [SATLUG] patching gcc's sourcecode?)

[_zip]

Thanks again for the responces. I'm having some problems still but with
compiling the patched source now.

I patched the source like so...

patch -p0 < protector.dif

...Everything looked like it went swell. I tared the source back up, did
the openssl md5, copied it to the right directory and edited the digest
with the md5 etc.

Now the build goes fine up until this point of compiling the gcc
compiler I patched. Here are the compilers lasts words. Sure enough it
stops on the part dealing with my patch.
