Thanks for the explanation. To clarify this statement: * If GCC 4.1.0 does not support the new ABI, but GCC 4.1.1 does support that, would it be possible to activate the support on the GLIBC 2.4 branch? * If GCC 4.1.x does not support the new ABI, but some later GCC does, will it be possible to either (a) activate the support on the GLIBC 2.4 branch, or (b) add it to the then-current development mainline for GLIBC? (I assume the answer to "b" is "yes", from the above, but I want to clarify because I'd hear that this was a now-or-never change in GLIBC.) Given that the GLIBC with the support is fully backwards-compatible with older GLIBCs, it seems that it would be possible to enable the support later on the GLIBC 2.4 branch, when compilers that can support the feature become available.
