[Bug-gsl] GSL testsuite fails when GNU make called with -jX where X > 1

[Thomas Anderson]

Hi all,
    I have noticed that gsl 1.16 (but not 1.15) fails the testsuite if
make is run with multiple jobs("make -j2 check"). I am on GNU/Linux
x86_64 with GNU make 4.0, GCC 4.8.2. The error is (not surprisingly)
independent of optimization level.

The contents of test.log are:

gsl: fprintf_source.c:164: ERROR: fscanf failed
Default GSL error handler invoked.

The full build error is (no error with -j1 option, the testsuite passes
fully):
