Also, having done a test build: various *tf* and *tc* libgcc functions end up getting built incorrectly (to use IEEE long double when the ABIs for those functions are supposed to use IBM long double) if you switch the default long double format. This affects at least __multc3 __divtc3 __powitf2 __fix{,uns}tf{di,ti} __float{,un}{di,ti}tf. -- Joseph S. Myers jos...@codesourcery.com
