README.MinGW says that the LIB.EXE tool is required to build dlls.

If that's no longer used by the makefiles it's a bug in the docs I guess.

I tried to pick the options from the scripts and I get

CC=i686-w64-mingw32-gcc CFLAGS=-m32 ./configure --host=amd64-gnu-linux
--target=i686-w64-mingw32      --prefix=/mingw

--enable-sp-funcs         --enable-widec
--with-fallbacks=unknown,rxvt         --with-tparm-arg=intptr_t
 --without-ada

and this build error:
