Hi, I was having problems building cross-i686-pc-mingw32/gcc (stage 2), when building libstdc++-v3 configure was complaining about win32 not being a valid thread model. Adding this to the toolchain.eclass solved my problem : [[ ${CTARGET} == *-mingw32 ]] && confgcc="${confgcc} --enable-shared --enable-threads=win32" (I didn't invent the info, it was taken from the x86-mingw32-build.sh script) HTH,
Forgot to mention gcc version, 4.3.1-r1.
thanks, added to cvs http://sources.gentoo.org/eclass/toolchain.eclass?r1=1.364&r2=1.365
