Hello,

   I have a problem runing the following program "test.c"

------
#include <stdio.h>
#include <sys/types.h>
#include <unistd.h>

main()
{
   int p;

   if((p = getppid()) == 1)
     printf("My parent is bad, ppid=%d\n", p);
   else
     printf("My parent is good, ppid=%d\n", p);

   exit(0);
}
--------

I build the program with the command

gcc -g -o test test.c

The problem is the following. When I execute the program in the command 
line

./test

I get the output: "My parent is good", but if I execute the same program 
under gdb

gdb ./test
(gdb) run

The output is "My parent is bad". I believe this is a bug in Cygwin's 
implementation of getppid().

Could someone please confirm this. Hopefully it is easy to fix.

Thank you.
