Crosscompiling 1.59 with i686-w64-mingw32-g++ fails

[Alexander Zimmermann <zimmermann@…>]

Using

using gcc : i686 : i686-w64-mingw32-g++ ;

in tools/build/src/user-config.jam

with i686-w64-mingw32-g++ (GCC) 4.8.2

and calling

./b2 toolset=gcc-i686 address-model=32 link=shared --stagedir=Win32 target-os=windows threading=multi threadapi=win32 variant=release --with-date_time --with-filesystem --with-graph --with-math --with-program_options --with-serialization --with-system --with-thread --with-timer

gives compiler errors

This patch resolves this problem:

With the above patch compiling works, but there is a linking error:

I am facing the same error.

There is a "fix" (pull request) here: ​https://github.com/boostorg/serialization/pull/19

(But I cannot get the sources from that page?!)
