Thanks for the report.

I understand that in some Windows environments, the 'windres' program
needs an option '--target=pe-i386' or '--target=pe-x86_64' so that it
produces an object file of the right format ([1] lines 91..102).

However, the only environment that is supported for building MSVC
binaries of GNU libiconv is Cygwin; see the INSTALL.windows file.
For this environment, the fix is to install the two packages
       - for creating 32-bit binaries: packages
           mingw64-i686-binutils,
           mingw64-i686-gcc-core
       - for creating 64-bit binaries: packages
           mingw64-x86_64-binutils,
           mingw64-x86_64-gcc-core
The configuration will then, based on the --host option, find
the correct flavour of 'windres' executables.

I have updated INSTALL.windows accordingly.

Best regards

       Bruno
