[gmp-4.3.1] make check fails (host: i686-pc-mingw32, build: athlon64-pc-linux-gnu)

[Heiko Lechner]

So, here is how I configured things:

After a "first stage" (binutils, mingwrt+win32api headers, gcc):

W32API:
--------

../w32api/configure --prefix="${BUILD_DIR}/mingw" 
--host="${BUILD_TARGET}" --build=`../gcc-4.4.0/config.guess`

make
make install

MinGW Runtime:
---------------

../mingwrt-3.15.2-mingw32/configure --prefix="${BUILD_DIR}/mingw" 
--host="${BUILD_TARGET}" --build=`../gcc-4.4.0/config.guess`

make
make check
make install

BINUTILS:
----------

../binutils-2.19.1/configure --prefix="${BUILD_DIR}/mingw" 
--target="${BUILD_TARGET}" --host=`../gcc-4.4.0/config.guess` 
--with-sysroot="${BUILD_DIR}" --disable-nls --disable-werror

make
make check
make install

GCC:
-------

../gcc-4.4.0/configure --prefix="${BUILD_DIR}/mingw" 
--target="${BUILD_TARGET}" --host=`../gcc-4.4.0/config.guess` 
--with-sysroot="${BUILD_DIR}" --enable-sjlj-exceptions 
--enable-threads=win32 --disable-win32-registry --disable-nls 
--enable-languages=c,c++

make
make check
make install

GMP:
-----

(after editing the configure script- see other post)

I found out that this could have something to do with libc, because 
sscanf returns a "wrong" value... So is this problem related to the 
MinGW runtime? Can I look over it?

TIA,
HEiko.
