- Subject: GNU C Library master sources branch, master, updated. glibc-2.15-1150-g0e4a3cd
This is an automated email from the git hooks/post-receive script. It was
generated because a ref change was pushed to the repository containing
the project "GNU C Library master sources".
The branch, master has been updated
via 0e4a3cd70809f9e67813fdbd781573f3081127cb (commit)
via 6704c645b05b8516915e07ccba4703b2924a9842 (commit)
