Comment (by jpye):

 I am now able to build stable IPOPT static libraries on both mingw32 and
 x86_64-w64-mingw32. But I can't reliably (1) eliminate the dependencies on
 libstdc++ and libgfortran due, apparently, to the different GCC versions
 between the MinGW32 build environment and the TDM-GCC compiler.

 Also (2), I seem to get weird stuff happening when I use '--
 build=x86_64-w64-mingw32' in my ./configure command. The 'config.log' (eg
 above attached) still incorrectly determining the architecture as i686-pc-
 mingw32, even though the compiler is clearly reporting x86_64-w64-mingw32
 from "gcc -dumpmachine". This seems like a bug that needs to be fixed,
 presumably by updating the build tools for IPOPT and maybe for the result
 of COIN-OR. In principle this needs to be fixed to allow eventually
 'proper' cross-compilation mingw32/mingw-w64 build environments to co-
 exist on one Windows machine.
