Without that, compilation was broken with VisualStudio:
So better solution than the SDL include, would be adding this to
"main.h", before <math.h> include:

Thomas, could you try that in your CI?
Not sure if that's really better - if I've got that right, M_PI and the
other constants are not part of POSIX or the C standard, so there might be
other systems where M_PI is not defined. OTOH, SDL_stdinc.h always makes
sure that it is defined, so unless we really really need to make dmaSnd.c
independent from the SDL headers, using SDL_stdinc.h is maybe the easier
Or if we really just need M_PI, maybe we can define it ourselves if it's
not already there with our own prefix ?
#define HATARI_M_PI 3.14xxxxx
That's just in case we really want to get rid of as many SDL includes as
possible ; if not, we can keep SDL_stdinc.h if it solves cases for all
possible combination of architectures / compilers.
