%description
GNU libiconv provides an iconv() implementation for use on systems
which don't have one or whose implementation cannot convert from/to Unicode.
It supports all the important encodings in use today.

The library is available as 32-bit and 64-bit.

If you are compiling a 32-bit program, no special compiler options are
needed.

If you are compiling a 64-bit program, you have to compile and link your
application with "cc -q64" or "gcc -maix64".

%build
# setup environment for 32-bit and 64-bit builds
export AR="/usr/bin/ar -X32_64"

# first build the 64-bit version
export CC="cc -q64"

# we need to include all shared members of the system wide /usr/lib/libiconv.a

# in /opt/freeware/lib/libiconv.a is found first - e.g. by setting $LIBPATH -
# then all system binaries will core dump as they don't find their required
# shared members in libiconv.a.
