It only makes sense for tchar.h to do this if the run-time library has
functions that implement the appropriate strlen clones. tchar is a non-POSIX
convenience that works a little differently in the M$ and Unix worlds.

According to my understanding (and Microsoft's) the API  

BOOL GetSystemPowerStatus(

    LPSYSTEM_POWER_STATUS lpSystemPowerStatus	
   );	

is only available as follows:

  Windows NT/2000: Requires Windows 2000.
  Windows 95/98: Requires Windows 95 or later.
  Windows CE: Unsupported.
  Header: Declared in winbase.h; include windows.h.
  Library: Use kernel32.lib

So you won't want to link this statically anyway (and so this libkernel32.a
has helped you by _not_ including the symbol, unlike Microsoft's
kernel32.lib). Instead do the LoadLibrary/GetProcAddress thing, check the
GetProcAddress return value and do something appropriate if it doesn't find
the entry-point:
