Compilation problem using gcc please help

[Sandeep M. Yelwatkar]

Hi,
I have encountered a problem while compiling a simple C++ program using
gcc.

GCC version    :  2.95.1
System type      :  Solaris 7

$cat try.C
#include  <iostream.h>
main()
{
    cout << "hello\n";
}
$
$ /opt/GNU/bin/gcc -o try -I/opt/GNU/include/g++3  try.C
cpp: fork: Interrrupted system call
$

Can you please tell me why the program doesn't compile, what could be
the possible reason's.

Thanks in advance.
Sandeep
