Details:

I'm building Octave 4.2.0 & 4.2.1 using the PGI 17.1 & 17.3 compilers,
respectively. When I run the

make -i -k check

I get this message

cd test && /bin/sh ../run-octave  --norc --silent --no-history
/cm/extra/apps/Octave/4.2.1/PGI-17.3_HDF5-1.10.0-patch2_openBLAS-0.2.19_FFTW-3.3.6-pl1/distro/test/fntests.m
/cm/extra/apps/Octave/4.2.1/PGI-17.3_HDF5-1.10.0-patch2_openBLAS-0.2.19_FFTW-3.3.6-pl1/distro/test
fatal: lo_ieee_init: floating point format is not IEEE!  Maybe DLAMCH is
miscompiled, or you are using some strange system without IEEE floating point
math?
make[3]: [check-local] Error 1 (ignored)

This did not happen with the Intel 17.0 or GCC 4.9.3 compilers, so it's
clearly an issue with the PGI compiler/runtime rather than the system
hardware.
