Hi Arthur,
gcc -isystem /usr/include hello.c -o hello
Note: I don't recommend doing this, since there are caveats about where the include files are pulled from, and in which order, for the system include path. What I do recommend is for you to talk with one of the system administrators and have them fix the environment so the compiler you are using is working properly without this kind of kluge.
HTH, --Eljay
