How to Apply a GCC Patch

I'm trying to apply this patch to GCC on MinGW to get i开发者_如何学Got to compile GDC 2, but I don't know how. (I'm still new to the internals of GCC, and even to *nix tools in general.) I know there's the patch command but I can't figure out how to use it, and I don't even know if I have enough information for this.

How do I apply the patch for GCC?

By default GNU Patch can be used by feeding a patch file to it from stdin (console input), e.g.:

patch < file.patch

There are many switches and options patch can use, the functionality is described here:

http://www.gnu.org/software/diffutils/manual/html_mono/diff.html#Invoking%20patch

patch and diff work hand in hand. A small demonstration is found on wikipedia.

Take a look at the patch manual pages. Just type man patch in a terminal window... typically i think you want to do a patch -p0 -i your_file.diff.
