Fatal error: 'bits/stl_relops.h' file not found

While trying to edit and download any robot programs from my personal PC to the new V5 cortex, Vex Coding Studio says there is an error and tells me

-- error -- In file included from ../vexv5/gcc/include/c++/4.9.3\tuple:38: ../vexv5/gcc/include/c++/4.9.3\utility:69:10: fatal error: 'bits/stl_relops.h' file not found #include

I found where the error is, but I do not know how to fix it.
Any help would be appreciated, as I have until Tuesday to figure it out and finish the program. Thanks in advance!

Nevermind, I managed to add the corresponding file myself.
