I have both too, and use gcc-config to switch when emerging qemu. If I select
3.4.6 with gcc-config then run 'make qemu' mtn complains:
version 'GLIBCXX_3.4.6' not found (required by mtn)
version 'CXXABI_1.3.1' not found (required by mtn)
Makefile: 28: *** Cannot determine version for monotone using "mtn -version".
Keeping gcc-config with 4.1.2 and tweaking Makefile setup-qemu to
include --cc=gcc-3.4.6 after --target-list=arm-softmmu gets further, but dies
after a bunch of errors in usb-linux-gadget.c
I have linux-headers-2.6.21 as suggested elsewhere, but it seems not to have
made any difference. This is on x86 - I've had even less luck on amd64.
