[Debian-med-packaging] Bug#835074: How to solve "'float log2(float)' conflicts with a previous declaration"

Hi,

pull-debians-source clustalo
cd clustalo-*

grep log2 . -R

a quick search seems to return
./src/clustal/mbed.c:#define log2(x)  (log(x) / 0.69314718055994530942)

there is also an interesting define
/* Has log2() */
#ifndef CLUSTAL_OMEGA_HAVE_LOG2
#define CLUSTAL_OMEGA_HAVE_LOG2 1
#endif
