Hi!
I looks (to me) like ape/math.h for 386 is missing the following two lines:

#define isnan(x) isNaN(x)
#define isinf(x) isInf(x, 0)

They are present in
/{68020|arm|arm64|power|sparc|sparc64|amd64}/include/ape/math.h. It
even looks like the lines are present for 386 in the stock Bell Lab's
distro. Any known reason for this irregularity? isnan() is used by
Netsurf's SVG-library.

While you're touching it, do you think you can unify the math.h stuff,
so they don't go out of sync?

	/$objtype/include/ape/_math.h:
		arch-specific math.h bits
	/sys/include/ape/math.h:
		arch-independent math.h, including <_math.h>

...never mind, I looked and did it. the only differences
between the copies were bugs.
