yann@1819: Subject: [PATCH 14/15] LT pthread_atfork: unhide
yann@1819: 
yann@1819: Trying to compile perl with uClibc new linuxthreads on arm.
yann@1819: I run into the problem that pthread_atfork is not available.
yann@1819: The problem was that it was synced with the glibc version, which has
yann@1819: compat ifdefs we do not need in uClibc. The inital checked in version
yann@1819: is right and works. So either revert the commit 2 years ago
yann@1819: or patch it with the patch attached I made for openembedded.
