Martin: I *think* this might be a bug in gcc6. According to [0]: Header <math.h> changes The C++ library now provides its own <math.h> header that wraps the C library header of the same name. The C++ header defines additional overloads of some functions and ensures that all standard functions are defined as real functions and not as macros. Code which assumes that sin, cos, pow, isfinite etc. are macros may no longer compile. Now the code in question is including <cmath>. Would it be possible that cmath might need some adjustment? Is the only way I see this can happen at all. [0] <https://gcc.gnu.org/gcc-6/porting_to.html#math.h> Thanks in advance, Lisandro. -- I'm doing a (free) operating system (just a hobby, won't be big and professional like gnu) for 386(486) AT clones.
