OK, this is a regression. mdadm-2.6.4-r1 compiles fine with both gcc-4.2.3 and 4.3.0. -r2 doesn't compile with either one, with the failure in the newly compiling mdassemble code. Having read the bug requesting mdassemble, I've a suggestion too. Make the mdassemble thing USE flag based as some of us either don't do mdraid until after boot or don't have an initrd/initramfs, assembling the root mdraid on the kernel command line directly, and thus don't need mdassamble, particularly when it's causing compile trouble. I'll attach emerge --info. Here's the errors (using gcc-4.2.3).

Created attachment 147695 [details] emerge --info On the errors in the originating comment, yes, that's how they were spit out; it said the previous declaration was "here" but didn't say where "here" was.
Oops! CFLAGS related, CFLAGS="-march=k8 -O2 -pipe" emerge -1 mdadm works (with both gcc-4.2.3 and 4.3.0). So marking invalid. I'll note which one it was when I figure it out, in case anyone else comes across the problem.
It was -combine. Should have known to try removing that one first! Sorry for the noise. (It'd still be nice to have USE flag control over mdassemble, however.) Duncan
