Query regarding GSoC

[Riva Malthiyar via Gcc]

Respected mentor,
I am Riva Malthiyar from India. I am experienced in C/C++. I saw the list
of projects in your GSoC project ideas and wish to work in one of them. In
the "Before You Apply" Section there is something related to compiler, I
did not understand that point. What kind of compiler is needed?
Regards
