This doesn't seem to be the reason why. Using the code:

function log2 (atom x)
   return log(x)/log(2)
end function
 
for i = 0 to 32 do
   printf(1, "%d: %0.16g\n", i & log2( power( 2, i ) ))
end for

with the EXW.EXE interpreter 3.0.2, I can't manage to get imprecise results
anymore, neither on my old system nor on my new system.  *LOL*

Maybe I made the tests with an older version of the interpreter, and
something has changed regarding this point (e.g. a different version of
the Watcom compiler was used to build the interpreter)? I only can guess.
