[Pkg-scicomp-devel] Bug#430296: 64-bit GCC and QHull

[Rafael Laboissiere]

Hi Brad,

I need your advice on a issue recently raised in Debian.  In a recent
version of GCC, the "long double" type changed from 64 to 128 bits on some
architectures.  A mass-bug filing had place in Debian and the QHull was
among the targeted packages [1].  I think that, in the case of QHull, it is
a false positive, probably triggered by some script that had seen:

$ cd /usr/include/qhull
$ grep -r "long double" .
./user.h: You may use 'long double', but many format statements need to be changed
./user.h: and you may need a 'long double' square root routine.  S. Grundmann

Could you please confirm to me that the QHull API does not depend on the
"long double" type, such that I can close the said bug report?

Thanks,
