Don't see anything against the DFSG, nothing requires DFSG to mean
GPL-compatible.

The below looks like the standard X license - one step up form Public

Below looks a lot like the X license, except for DEC. However, I'll let
the lawyers decide if the first line is sufficient to allow redistribution
of modified software, not just modify for your use, and redistribute the
original.

The below looks like an even more relaxed version of X. Again about the
right to redistribute modified code (I think it does, but I'll let the
lawyers say if it's explicit enough or not).
