>Description:
	When building ports/math/py-numeric, the following condensed errors
	are displayed: (wrapped for safety)

	cc -fno-strict-aliasing -DNDEBUG -O -pipe -D_THREAD_SAFE
	-DTHREAD_STACK_SIZE=0x20000 -O -pipe -fPIC -DHAVE_INVERSE_HYPERBOLIC
	-IInclude -IPackages/FFT/Include -IPackages/RNG/Include
	-I/usr/local/include/python2.3 -c Src/umathmodule.c
	-o build/temp.freebsd-4.8-STABLE-i386-2.3/Src/umathmodule.o
	Src/umathmodule.c:1952: `acosh' undeclared here (not in a function)
	Src/umathmodule.c:1952: initializer element is not constant
	Src/umathmodule.c:1952: (near initialization for `arccosh_data[0]')
	Src/umathmodule.c:1952: `acosh' undeclared here (not in a function)
	Src/umathmodule.c:1952: initializer element is not constant
	Src/umathmodule.c:1952: (near initialization for `arccosh_data[1]')
	Src/umathmodule.c:1953: `asinh' undeclared here (not in a function)

	I have not built this module since I needed it for the Python 2.2
	series.  I am not sure if the new Python 2.3 changes are what may
	be contributing to this problem regarding reading the distutils
	setup files.


>How-To-Repeat:
	Try to build the py-numeric port.
>Fix:

	Immediately when I saw the familiar math library functions not being
	defined, I checked for math.h being included (it is) and the -lm flag
	passed (which it's not) to the compiler/linker. I looked in the
	setup.py utility, used to aid in compilation and installation of the
	software, and it seems to know about -lm as indicated by the line:

	mathlibs = ['m']

	Which, I believe, should add the -lm flag when compiling, though it
	does not, as shown from the previous cc line.

	Hope this helps fix the problem.
