Here's a little issue I found w/ the new Python 2.7.3 port: acme# cd /n/sources/plan9/ acme# grep isinf */include/ape/math.h arm/include/ape/math.h:#define isinf(x) isInf(x) mips/include/ape/math.h:#define isinf(x) isInf(x) power/include/ape/math.h:#define isinf(x) isInf(x) sparc/include/ape/math.h:#define isinf(x) isInf(x)
isinf() is missing from 386 & amd64 APE headers. Of course, having only one argument to isInf(x) will give you the following if you actually try to use it: /usr/jas/src/cmd/cpython/Plan9/../Python/bltinmodule.c:2173[stdin:16039] not enough function arguments: isInf So it's probably safe to just have #define isinf(x) isInf(x,0) in /*/include/ape/math.h
