Include directory for gcc

[Arthur Niswar <niswar at int dot uni-karlsruhe dot de>]

I have a problem in compiling a very simple program with gcc on Solaris. 
Here it is:

# gcc hello.c -o hello
hello.c:0: /usr/local/include/.: Permission denied

The program hello.c itself:

# less hello.c
#include <stdio.h>

int main()
{
  printf("Hello World!\n");

  return;
}

As a fact, most of the computer in my lab are Linux, and only several of
them (if not just 1!) are Solaris. So I suspect the gcc search path for
include files is configured for Linux (1st search in /usr/local/include). 

How can I "direct" gcc to first search in the normal /usr/include ? 

Thanks!
