The error persists. When building crt/lib64: '_libm_dummy.c:1:0:
sorry, unimplemented: 64-bit mode not compiled in'
It is also unclear, why it is used i686-pc-mingw32-gcc, while
i686-w64-mingw32 must be used. In PATH it is available:

configure flags:

--prefix=$PREFIX
--enable-lib32

I have read wiki. I have built x86-x86_64 and x86_64-x86_64 succesfully.
But wiki contains very little information about building the multilib compiler.
And there is almost not a word about host/build/target. From what
options that depends, on what it influences, for what, why, and so
on... - Everyone just has to guess and learn someone's scripts...
Maybe for some it's obvious, but not for those who read wiki.
Thanks.
