title: Undefined reference to WinMain in Cygwin
body: <p>I am trying to compile and having following problem</p>
  
  <pre><code>$ gcc errlib.c -o errlib.o
  
  /usr/lib/gcc/x86_64-pc-cygwin/4.8.2/../../../../lib/libcygwin.a(libcmain.o): In function `main':
  /usr/src/debug/cygwin-1.7.30-1/winsup/cygwin/lib/libcmain.c:39: undefined reference to `WinMain'
  /usr/src/debug/cygwin-1.7.30-1/winsup/cygwin/lib/libcmain.c:39:(.text.startup+0x7e): relocation truncated to fit: R_X86_64_PC32 against undefined symbol `WinMain'
  collect2: error: ld returned 1 exit status
  </code></pre>
  
  <p>Any suggestions? These files are well tested and generated the code fine before but now i think there might be some cygwin settings or so ... m compiling on windows 8 on cygwin.</p>
