new gcc wrapper, entirely specfile based the _concept_ of this wrapper has been tested extensively, but the integration with the build/install system, and using a persistent specfile rather than one generated at build-time, have not been heavily tested and may need minor tweaks. this approach should be a lot more robust (and easier to improve) than writing a shell script that's responsible for trying to mimic gcc's logic about whether it's compiling or linking, building shared libs or executable files, etc. it's also lighter weight and should result in mildly faster builds when using the wrapper.

*link:
make gcc wrapper rewrite link options rather than just extending them this is not tested yet, but should work to get rid of unwanted --hash-style=gnu hacks present in some distro-patched gcc versions.
