Title: What is HKEY type ???





Hi,


I want to compile a application with cygwin. 
So, I run make... But there is a error :
In the /usr/i686-pc-cygwin/include/windef.h file, there is a error line 177.
The line is typedef HKEY *PHKEY; 
But, the HKEY type is defined nowhere (and some others files -winreg.h, ...- use this type)


All these files are cygwin library. 
Where can I found the decaration of this type ?


Thanks for answer.


Gilles.
