If you try and build libstdc++ without patches you get the same issues. I'm planning on sending a submission to gcc-patches, but in the interim, you can see the kind of simple fixes we had to make.
Check wrn/coreip/ for the include as well. Since GCC doesn't support setting target-specific include directories without some really bad hacks, I had to put in some temporary stubs to redirect the includes. I'm thinking of restructuring the system headers so one no longer needs this cruft, but I'm pushing the boundaries of fair use as is :-(
The other thing that is prone to break is stuff that has to do with the filesystem. Look at the patches for examples of how stuff had to be changed.
Luckily, there were only a few files that screwed up for libstdc++. Hopefully libgfortran is similarly simple. And if you need any help you can post!
