[Bug-gsl] gsl-1.16 test fail

[jr]

hi,

re  gsl-1.16 test fails


downloaded the source from ftp.gnu, configured with

  $ CFLAGS='-march=i686 -mtune=i686 -O2' ./configure --with-gnu-ld

then

  $ CFLAGS='-march=i686 -mtune=i686 -O2' make

then (as shown in INSTALL)

  $ GSL_TEST_VERBOSE=1 make -k check


one test failed, in 'poly', the following are grep'd from the
'poly/test-suite.log' file:
