Create a file called 'stderr.c':
int
main(int argc, char **argv)
{
 dup2(1, 2);
 argv++;
 execvp(*argv, argv);
 perror(*argv);
 exit(1);
}
Compile this:
gcc -o stderr -g stderr.c
The program stderr will redirect all error output to the same place as
stdout:
stderr gcc -c stderr.c > gcc.out
This will probably only work with cygwin.dll programs, though.
