Re: cdb for Win32?

It can be ported, both to cygwin and native win32.
cygwin compilation should work without any issues (not sure if any 
source changes are needed at all).
For the "pure" win32 port, it's mainly about emulating unistd.h mmap and 
munmap calls, I used the code below,  curtesy of Imagick graphics 
package developers:
--------------------------------------------------------
#ifdef __WIN32__
  #include <windows.h>
/*   m m a p           ===      got it from imagick sources
%  Method mmap emulates the Unix method of the same name.
%  The format of the mmap method is:
%    void *mmap(char *address,size_t length,int protection,
%      int access,int file,off_t offset)
*/
void *mmap(char *address,size_t length,int protection,int access,
  int file, off_t offset) {
  void *map;
  HANDLE handle;
  map=(void *) NULL;
  handle=INVALID_HANDLE_VALUE;
  switch (protection)
  {
    case PROT_READ:
    default:
    {
      handle=CreateFileMapping((HANDLE) 
_get_osfhandle(file),0,PAGE_READONLY,0,
        length,0);
      if (!handle)
        break;
      map=(void *) MapViewOfFile(handle,FILE_MAP_READ,0,0,length);
      CloseHandle(handle);
      break;
    }
    case PROT_WRITE:
    {
      handle=CreateFileMapping((HANDLE) 
_get_osfhandle(file),0,PAGE_READWRITE,0,
        length,0);
      if (!handle)
        break;
      map=(void *) MapViewOfFile(handle,FILE_MAP_WRITE,0,0,length);
      CloseHandle(handle);
      break;
    }
    case PROT_READWRITE:
    {
      handle=CreateFileMapping((HANDLE) 
_get_osfhandle(file),0,PAGE_READWRITE,0,
        length,0);
      if (!handle)
        break;
      map=(void *) MapViewOfFile(handle,FILE_MAP_ALL_ACCESS,0,0,length);
      CloseHandle(handle);
      break;
    }
  }
  if (map == (void *) NULL)
    return((void *) MAP_FAILED);
  return((void *) ((char *) map+offset));
}
