Compiler Command-line Options
Example
void foo(void)
{
long long i; /* okay in non-strict C90 */
}
Compiling this code with --strict_warnings generates a warning message.
Compilation continues, even though the expression long long is strictly illegal.

2.1.114 --sys_include
This option removes the current place from the include search path.
Quoted include files are treated in a similar way to angle-bracketed include files, except
that quoted include files are always searched for first in the directories specified by -I,
and angle-bracketed include files are searched for first in the -J directories.
