I've observed this binary linking successfully on Debian but not on
Ubuntu. The package uses an autotools build system.
On Ubuntu, gcc link complains about unresolved reference to ceilf, even
though -lm is in the linker command line
Can anybody comment on the correct way to go about this? On both
platforms, autoreconf is executed as part of the package build from
debian/rules and there is one patch against configure.ac, for supporting
HURD and kFreeBSD kernels.
