title: GCC with Cygwin/Win7: missing syscall.h
body: <p>I am trying to compile a linux c++ source code on Windows 7 Cygwin and getting following error:</p>
  
  <pre><code>$ make
  getconf: Unrecognized variable `LFS_CFLAGS'
  gcc -O3 -Wall -Wextra -g -DVERSION='"v1.1.0"'  -c src/main.c -o src/main.o
  src/main.c:10:25: schwerwiegender Fehler: sys/syscall.h: No such file or directory
   #include &lt;sys/syscall.h&gt;
                           ^
  Kompilierung beendet.
  Makefile:48: recipe for target 'src/main.o' failed
  make: *** [src/main.o] Error 1
  </code></pre>
  
  <p>I googled this but hadn't any success. Any ideas?</p>
