Code looks valid.

                                            ^^

The SX designation on a 486 means that your math co-processor (IOW,
floating point unit) is disabled.  Therefore, any program you right to
use floating point will have to use an floating point emulation
library to do the math.  Maybe GNAT has some kind of a problem with
this.  See if there is a compiler switch to turn FP emulation on/off,
and turn it on if it exists.

Just a shot in the dark, but it is worth a try.
