Summary: declaration of `y1' shadows a global declaration

Initial Comment:

When using math.h on Darwin, the y1 variable causes
lots of warnings.

../../pd/src/g_canvas.h:247: warning: declaration of
`y1' shadows a global declaration
/usr/include/architecture/ppc/math.h:483: warning:
shadowed declaration is here

Renaming y1 in g_canvas.h would fix this problem.

Whatever about calling functions y0,y1,yn, they've been
there since almost the beginning of unix. They're Bessel
functions defined in <math.h>. You won't be able to move
them out of it. This suggests that the -Wshadow warning is
of questionable use. I'd turn it off, personally.

a) has this been fixed already? (i cannot reproduce this
anymore; also the pd(-extended) buildlogs do not show this
warning)
b) i don't think that this is a bug in pd; no global include
file (/usr/include/architecture/ppc/math.h) should use
global variable names like "i", "y1" and the like.
