#441 Tests fail with uselongdouble perls in PDLA (works in PDL-2.x master)

[Slaven Rezic]

If perl is compiled with -Duselongdouble, then some tests in the ETJ/PDLA-2.013003.tar.gz testsuite fail.

On linux:

#   Failed test 'q[e] returns exp(1)'
#   at t/pdl_from_string.t line 301.

PDLA split from PDL before the PDL-2.016 release. This problem has been fixed in the PDL-2.x code but it never was re-synchronized into PDLA.

Leaving this open as a reminder if anyone picks up PDLA.
