sigaction test failure on FreeBSD 9.1 when pthread is used

[Daiki Ueno]

Hi,

On FreeBSD 9.1, I got an assertion failure in test-sigaction.c when the
test case is compiled with:

  $ gnulib-tool --create-testdir --dir=test-sa-openmp sigaction openmp
  $ cd test-sa-openmp
  $ ./configure --enable-openmp
  $ make
  $ make check
  ...
  test-sigaction.c:69: assertion failed
  Abort trap (core dumped)
  FAIL: test-sigaction

It seems -fopenmp flag causes the error.  It can also be reproduced
without openmp, but with CFLAGS="-O2 -pthread".

Regards,
