In Ubuntu, we've applied the attached patch to achieve the following:
* 041_rename_round.patch: rename round() in utils/gtf/gtfcalc.c to fix
FTBFS due to conflict with the one defined in math.h (LP: #449747).
We thought you might be interested in doing the same.
The build fails with the following error:
