Hi all,

Cygwin works great for me in providing POSIX tools for Windows, but
when I tried to to compile something of my own, I immediately ran into
problems.

Compiling my Hello World application didn't complain but when running
it I didn't get any output. My compilation command was like this:
   gcc -Wextra -Wall -o hello hello.c
And my source code is below between "---" markers:
----------------------------------
#include <stdio.h>

int main() {
  printf("Hello, World!\n");
  return 0;
}
----------------------------------
I also tried by redirecting output, like "./hello > output.txt" but
that created only an empty file, proving that my write permissions
were sufficient, I suppose.
Then I thought that maybe the problem is in connecting to stdout and I
tried by direct file access:
---------------------------------
#include <stdio.h>

int main() {
  FILE *of = fopen("./outfile.txt", "w");
  if(of) {
    fprintf(of, "Hello, World!\n");
    fclose(of);
  }
  return 0;
}
---------------------------------
However, that didn't create the "outfile.txt" file.

I did those experiments in a Windows 10 environment, I think it is
Windows 10 Enterprise. I have installed Cygwin without administrator
privileges, in 2018.

A practical work-around has been to use MinGW for compilation.

Thanks for any help,
Vesa
