Test failures with edge cases in slatec-fn functions

[Michael Goffioul]

Hi,

When I run the octave test suites (octave dev branch, MSVC +
gfortran), I get various errors due to slatec-fn functions not
handling edge cases, like:

erfc(Inf)
atanh(1)
...

The result is that the fortran routines throw an exception (e.g. "X SO
BIG ERFC UNDERFLOWS"). Is this expected from the slatec-fc functions?

Michael.
