I noticed this pervasive use of Long_Long_Float early on, and ended up
spending a fair bit of time looking through the RTS code for the
Right Way. I've gotten everything to work (so far) by doing the
following:

1. Modifying all the IEEEX_ attributes to be the same as the IEEEL_
attributes in Ttypef.ads.

2. Defining LONG_DOUBLE_TYPE_SIZE to be 64 in my GCC target include file,
config/i386/rtems.h

This finally allows me to use GNAT/RTEMS with software floating-point.

Does this sound right you, Robert? I suspect there's a cleaner way to
do this, or perhaps there's something I've forgotten...

Thanks for your feedback.
