Recompiling de distro

Question

I've been recompiling my entire system with the ABS packages, and while almost all packages compiled well under gcc4.3, some packages had trouble with it.
So I've discovered the 'bugs' and made some patches. I would like to share them with the community. (I don't' know if this is the right place, but I guess it is)
Nautilus (2.22.5) had problems with one include:

I have other paches, but I couldn't find them. When I do, I'll post the rest

Answer 1

I'm using the /var/abs PKGBUILD's and copying them to my home directory. Then I compile with makepkg.
It's a hard work, since I was doing it one by one, starting from the core packages and up.  Some of them are giving me some headaches, like Xgl. Xgl seems to miss headers from Xorg 7.0.2 (arch uses 7.0.3). With these problematic packages I had to search for a patch or a new version. With the Xgl I didnt find a solution yet. I wanted those compiz-fusion effects..
Also worth to note, some PKGBUILD files have options like --without-sse that may hinder speed.:/
Aswering your question, I could notice a considerable increase in speed. Some apps open quite faster. And I'm using conservative CFLAGS (-march=core2 -fomit-frame-pointer -O2).
