* gthr-posix.h (__gthread_active_p): Use the Solaris implementation
for FreeBSD as well. This is the fix for __gthread_active_p() returning false positives which was committed as rev. 1.1.1.8.2.1 to RELENG_7 but now looped back to the vendor branch via the GCC repository and relicensed to be GPLv2 by me. Thanks go to gerald@ for getting the fix approved upstream and for committing to the GCC repository. PR: 119289 Approved by: core
