> Unfortunatly, unbundled complers (eg GCC>3.0) typically don't use system supplied files such as crtbegin.o - instead they supply their own. Consequently, an unbundled compiler won't include the crtbegin.o .note section and, in turn, won't be able to generate binaries that can be run on NetBSD-current.
IMHO, the compiler should be fixed to include the proper .note section
on NetBSD hosts.
