Run into the same problem.

Workaround is:
- backup existing libstc++ from /usr/lib/ && ldconfig
- move the just built libstdc++  there && ldconfig
- build and install/package gdc
- move backed up libstdc++ back to /usr/lib && ldconfig

Just beating the compiler to do that at the moment :-)

My steps so far:
- started with gdc-0.23-devel branch
- fixed line-endings as Gregor suggested :-)
- used DMD 1.018 patch from Gregor and 

- ported patches from David to gcc-4.2
- replaces various instanced of build() with build2() or build3()
- used common option framework in GCC

Latest problem: "gdc: unknown spec function 'd-all-sources'" when
gdc tries to built libphobos. Can I built the d-all-sources functionality
with "-combine" in newer gcc?

Any help is appreciated. I'll publish my changes as patches like 
David provides later. I run Linux/Ubuntu Feisty Fawn.
