blocking problem in StrictMath.remPiOver2

[hultul]

I've accidently found a blocking problem in StrictMath.sin(double a)
during mauve testing of classpath-0.12. (for example, blocked when
a=1e50)
The reason was that 'do~while' had caused infinite loop in
StrictMath.remPiOver2(double[], double[], int, int). The 'do-while'
goes to infinite loop when recompute=true.

>From the review of fdlibm library in classpath, It seems to be needed
a simple correction of StrictMath.remPiOver2 as follows.
