math.h test

[Matti Ilgmann]

Hi,

I have written a few lines to test math.h.  I am not a programmer, so 
please tell me
wether these lines are OK.  I will then complete the test.  On my 
system a "make check"
has this output:

make  check-TESTS
make[1]: Entering directory `/home/matti/hurd-l4/libl4/tests'
PASS: t-l4-kip
PASS: t-l4-message
PASS: t-l4-math
==================
All 3 tests passed
==================
make[1]: Leaving directory `/home/matti/hurd-l4/libl4/tests'

Thanks,
Matti
