 Check out gcc from the gcc subversion repository:

 Darwin special: the gcc configure script thinks darwin doesn't support dynamic
 libraries and concludes that plugins won't work.  Delete or improve the check.

 Step 2: Build the plugin
 ------------------------
 
-In the Makefile, set the GCCSOURCE_DIR variable to point to the place you
-checked out the gcc repository, rather than to where I checked it out.
-Set the GCCOBJECT_DIR to point to the place you built the repository.
-Admire the awfulness of the build system, and make a mental note to rewrite
-it properly.

-Build the plugin using "make".  The end result of the build is a shared
-library, dragonegg.so.
+Build the plugin like this:
+  GCC=PATH_TO_JUST_INSTALLED_GCC make
+If the gcc installed in step 1 occurs in your path with the name gcc-4.5 (maybe

 Darwin special: "-shared" doesn't result in a correct dynamic library on darwin,
 use "-Wl,-flat_namespace -Wl,-undefined -Wl,suppress -dynamiclib" instead.

 Run gcc as usual, but pass -fplugin=./dragonegg.so as an extra command line
 argument.  Make sure you use the gcc you installed above, not the system gcc!
 
-Currently the plugin isn't capable of compiling much - you have been warned.
