Hello,

1) I need an exact constructions kernel for the computation
of intersections and orientations. According to an older
posting, Gmpq is not thread-safe. Is this still true? Is
a #define necessary to specify thread-safety?

2) I assume that a Gmpq value, written to a file using
outFile<<q and read again is the same? Just to be sure
that the exactness is not lost in this step.


Best,
Bernhard
