> I am interested in contributing to gcc for the gsoc 2016. Unfortunately, it seems GCC did not apply to participate in GSoC 2016 and the deadline passed already: https://summerofcode.withgoogle.com/organizations/?sp-search=GCC It also seems we did not apply last year either (at least https://gcc.gnu.org/wiki/SummerOfCode does not show any accepted projects for 2015).
As usual, GNU applied to participate in this year's GSOC and was accepted as a mentoring organization. GCC related projects can be performed under the umbrella of the GNU org, provided there are suitable mentors. Please see http://www.gnu.org/software/soc-projects. The relevant mailing list is https://lists.gnu.org/mailman/listinfo/summer-of-code
