float_package, float_generic_pkg, etc. are available as part of IEEE Std 1076-2008 (http://standards.ieee.org/downloads/1076/1076-2008/, the zip file, when expanded subdirectory ieee). In general you’d have to back port them to an earlier revision. It could be onerous, they’d take advantage of changes to the standard. David Bishop used to make back ported versions available on eda.org for -1993, (eda.org sponsored by Mentor will be closed down shortly, See http://www.eda.org/fphdl/, VHDL-93 versions of the VHDL-2008 packages, try ZIP file of all the packages <http://www.eda.org/fphdl/vhdl2008c.zip>). > > How can I add this new library to GHDL?

Simply dumping the sources in the IEEE library source doesn’t provide access. (And opens a can of compatibility worms). > I'm using GHDL 0.25 on Windows. If you were to download ghdl-0.33 for Windows (http://sourceforge.net/projects/ghdl-updates/files/Builds/ghdl-0.33/, the link to ghdl-0.33-win32.zip), you’d have the packages installed. There’s a command line flag for revision -2008 (--std=08, given after a command (-a/-e for analysis/elaboration) of the standard you could pass to provide access.
