Currently, OpenACC 2.0 is in gomp-4_0-branch, but this email: https://gcc.gnu.org/ml/gcc/2015-01/msg00032.html
says that gcc 5.0 will enter stage 4 on Friday 16th January, and from that point onward, only bug fixing patches will be accepted. So will gomp-4_0-branch be able to be merged into the trunk before Friday 16 January?
