GDE/MUSCLE/src/subfams.cpp redefines INFINITY

[guest]

Hi, arb 6.0.6 fails to build on macOS 10.15. The error is in this file:

browser:trunk/GDE/MUSCLE/src/subfams.cpp​

It tries to define INFINITY which has already been defined by the system math.h header.

The error is:

src/subfams.cpp:4:13: error: functions that differ only in their return type cannot be overloaded
const float INFINITY = float(1e29);
