Is lint supposed to be some gdb command? as I don't see to find it out.

If you are trying to statically check your main.c code with lint [1], you 
should do it outside gdb. They are completely independent tools. In gdb 
you tipically set your breakpoints etc and then (gdb) run (see eg. the gsl 
manual[2], or [3]). Or am I missing something here?
