The problem is that gcc-2.8.1 takes  math.h from $DJDIR/include
while correct version is in $DJDIR/lib/gcc-lib/djgpp/2.81/include.
This is so because it is no more need to keep $DJDIR/include
in include files search path as gcc-2.8.1 knows the default search 
directories. I suggest take a look (and perhaps use) a version of
DJGPP.ENV which is included with gcc281b.zip (in directory 
/gnu/gcc-2.81)
