I'll fix that; I think the best solution is to use GMX_REAL_MAX, as HUGE_VALF isn't in C89, and might fail to compile, e.g., on Windows... I think that on most implementations, HUGE_VAL equals infinity, and thus works even in this context, but apparently not on all. And as Szilard said, this doesn't affect mdrun, only g_select at the moment. Depending a bit on what the compiler does, it might even work correctly despite the warning.
