  4. Subject: [PATCH 14/15] LT pthread_atfork: unhide
    5. 

  5. 

  6. Trying to compile perl with uClibc new linuxthreads on arm.
    7. 

  7. I run into the problem that pthread_atfork is not available.
    8. 

  8. The problem was that it was synced with the glibc version, which has
    9. 

  9. compat ifdefs we do not need in uClibc. The inital checked in version
    10. 

  10. is right and works. So either revert the commit 2 years ago
    11. 

  11. or patch it with the patch attached I made for openembedded.
    12.
